1. How to select different data providers in business objects? 

Once you have your report generated, right click in the left window (your variables) click on "New Data Provider" follow the wizard. & you are done. If trying to use diff. data provider for different reports, after creating 1 report, right click on the Report1 tab located at the bottom, click insert new then the procedure is same to add data provider.

2. When we use aggregate awareness function in designer? 

In order to solve fan trap in business objects we either create alias table or aggregate awareness function Through aggregate navigation we can also select the compatible as well as incompatible objects Ex:-year, quarter, month, week, and day Year:-quarter, month, week, and day are compatible objects Quarter:-year  class is incompatible and month, week, day is compatible. We specify the objects in descending order  3. What is Business objects Repository? 

It is nothing but metadata. 4. Is there any other repository domain rather than...

There are only three main Domains Security, Universe and document. You can have multiple Universe and Documents domains in a repository but only one Security domain. 5. What is a Bo repository 

Its A Semantic Layer Which Stores The Bo Users N Their Privileges Repository means set of database tables, Business object store security information e.g. user, group, access permission, user type etc., universe information e.g. objects, classes, table name, column name, relation ship etc.and document information. Repository is data accounts which contain three domains in each one type. You can create the repository any where .the security domain has the user security info and other domains address. You can have more than one repository but you can use which one u specifying on the time of login. The address info of the security domains is stored in the .key file if WebI it’s in the Bomain.keyfor more refer the cindi howson book and visit her web www. Askcindi.com BO repository is a set of db tables which holds the metadata information. This Bo repository is divided in to 3 domains Security, universe, and document domain. This metadata holds all the information related to users groups their  privileges...........except the "supervisor" this is the super user of Bo rep.the supervisor info is stored BOMain.key which is stored in default theme dir of Bo. BO Repository is a set of related data structures of BO stored in a database. It contains tables of Security, Documents and Universe Domains Generally Repository is the Metadata BO 5.0 Repository create/maintain 50 tables, they are distributed as follows 25 tables for Security domain 24 Table for Universe domain 1 Table for Document Domain in 6.5.1 repository •

25 tables in sec.domin 1 table in doc domain 31 tables in uni domain It is a metadata Can some one provide the BO XI rel 2 repository Domains (Number of tables for each domain)... A context is simply a list of joins denoting a path between tables. Contexts are set to identify alternative routes in the universe structure. BusinessObjects detects a context for each alternative route. Contexts identify tables which are incompatible within the same SELECT statement because the wrong results will be produced. •

6. What is domain? How many are there in a basic setup? What are they? 

Domain is nothing but logical grouping of system tables, there are three domains usually in a basic setup, and they are Secure, Universe, and Document. Business objects are sometimes called domain objects (where the word domain means the business), and a domain model represents the set of domain objects and the relationships between them. 7. When is the Repository created? 

In 5i/6i versions after installing the software, whereas in Xi version a repository is created at the time of installation. 8. Can we have multiple domains? 

Yes. (Security domain can not be multiple). 9. How do you restrict access to rows of a database? 

In XI version it can be do

10. In a report can we hide a particular object? 

Yes we can show/hide a particular object in a table by using the pivot tab of the format table dialog box 11. Difference between compatible and incompatible objects? 

When an object is at the same or higher level of aggregation as the table, it is compatible with the table. -

When an object is at a lower level of aggregation than the table (or if it is not at all related to the table), it is incompatible with the table. We can select or choose compatible n incompatible objects through aggregator  navigation in the designer. With this method the performance increases tremendously. Instead of checking for each n every object only the compatible objects are only looked for  aggregate awareness. Year:-month, quarter, week, day are compatible but customer class is incompatible -

12. Can you please clarify the difference between compatible and incompatible objects?  When we will use these two? 

When you are defining Aggregate tables in Universe design, you need to create hierarchies for aggregated objects, for that you need to make the relative objects incompatible (the objects which are of lower level of aggregation -- not of hierarchy you have Year, Quarter, Month, Day as a hierarchy, while aggregation, you need to define as follows Year - Quarter, Month, Day Compatibles Quarter - Month, Day Compatibles, Year Non-compatible Month - Day Compatible, Year, Quarter Non-compatible 13. Detail 

Provide a description of a dimension, but are not the focus For analysis. For example Phone Number  Detail objects are attached to dimensions; one cannot drill on details nor link on details when linking multiple data providers. While Customer ID would be a dimension, customer name, address, phone and soon should be details. 14. Measure

Convey numeric information which is used to quantify a Dimension object. For example Sales Revenue 15. What is an object? 

It is an instance of class, its nothing but an entity. In Business Objects products an object is a named component in a universe that Represents a column or function in a database. Object qualification represents what kind of object is that, usually we have three types of object qualifiers they are measure, dimension, detailed. An object is a named component that maps to data or a derivation of data in the Database. The name of an object should be drawn from the business vocabulary of the targeted user  group. For example, objects used in a universe used by a Product manager could be Product, Life Cycle, or Release Date. A universe Used by a financial analyst could contain objects such as Profit Margin, and Return on Investment. In Designer, objects are qualified as one of three types: dimension, detail, or Measure. -

Object qualification represents what kind of object is that, usually we have three types of object qualifiers they are measure, dimension, detailed. -

16. What is a loop? How can we overcome? 

- Loop is nothing but a closed circular flow; it can be overcome by making use of Alias and Context. 17. How does a context resolve a loop? 

A context resolves a loop by defining a set of joins that specify one specific path Through tables in a loop. It ensures that joins are not included from different paths Within the same SQL query. 18. While resolving loops, how to decide whether alias or context to be used? Describe 19. What is the use of alias and context? Which is the better for solving the loops? Why?  Why we use alias and why we use context?  20. What is a Loop? 

A loop is a set of joins that defines a closed path through a set of tables in a Schema. Loops occur  when joins form multiple paths between lookup tables. 21. What is a loop? How can we overcome? 

Loop is nothing but a closed circular flow; it can be overcome by making use of Alias and Context. 22. How does an alias break a loop? 

An alias breaks a loop by using the same table twice in the same query for a Different purpose. The alias is identical to the base table with a different name. The data in the alias is exactly the same as the original table, but the different Name “tricks” SQL into accepting that you are using two different tables. 23. Create an alias to break a loop caused by shared lookup tables

A sales database holds information about customers living in different countries. These customers can place orders for goods that can be delivered by a number  Of couriers or shipping companies. 24. Determining when an alias is not appropriate to break a loop

Creating an alias to resolve the loop described above is not the optimal solution. In this case, the use of contexts is a better solution. The following example Describes why aliases are not appropriate, and why contexts are a better solution In this case. If you try to identify the lookup table used for more than one purpose, it is not clear  If it is the PRODUCTS table, or the CUSTOMERS table.

25. What is a context? 

Contexts are a collection of joins which provide a valid query path for  Business Objects and Web Intelligence to generate SQL. 26. What is the difference between detect alias and detect context? 

Answer we should use Detect Aliases and Detect Contexts to formally identify and resolve loops. I.e. if a loop contains only one lookup table then the loop can be resolved by detecting the alias. If a loop is having 2 or more fact tables (multiple fact tables) then the loop can be resolved by detecting context. 27. What do prefer an Alias or a context? Why?  28. What is a Chasm Trap? 

. A chasm trap is a common problem in relational database schemas in which a Join path returns more data than expected. A chasm trap is a type of join path between three tables when two "many-to-one" joins converge on a single table, and there is no context in place that separates the converging join paths 29. What is a Fan Trap? 

A fan trap is a less common problem than chasm traps in a relational database Schema. It has the same effect of returning more data than expected. A fan trap is a type of join path between three tables when a “one-to-many” join links a table which is in turn linked by another “oneto-many” joins. The fanning out effect of “one-to-many” joins can cause incorrect results to be returned when a query includes objects based on both tables. 30. How Do You Resolve a Fan Trap? 

There are two ways to solve a fan trap problem. • Create an alias for the table containing the initial aggregation, then use Detect Contexts (Tools > Detect Contexts) to detect and pr opose a context for the Alias table and a context for the original table. This is the most effective way To solve the fan trap problem. 31. What is a fan trap in Business Objects? 

Actually FAN TRAP is a problem that occurs in Universe Level. Loop occurs while we design the universe. Two Types of Loop Problem: 1) FANTRAP PROBLEM solved by ALIAS METHOD:

Definition: Two One-to-many table links each other is in turn linked another one-to-many table. 2) CHASM TRAPS PROBLEM solved by CONTEXT METHOD:

Definition: Two Many-to-one table converges on one single lookup table. Loop can be detected while INTEGRITY CHECK is done. An option is there as "Check for  LOOPS" available. By "Detect Loop" we can choose what to be applied for solving the loop.

 When there is a series of one to many join in the tables, a Fan trap is resulted. This may cause incorrect results to be returned when a query includes objects based on both tables. For example: Associate, A Project,  Dept tables. One associate may work for N Projects, and those N projects may be Executed by N Dept....The report executed with the Associate table and the Dept table objects may produce that One Associate belongs to many departments. To avoid this Create an Alias table for Project A, which is A joined to the Associate as One to one mapping table. Create an Alias table for Dept, which is A joined to the Project as One to one mapping table. That means one associate, will be shown working for one project, and one project belongs to one dept. Which will now result in one associate working for one Dept.?  There are many other methods to solve Fan trap!! Creating Manual Context, Using @ Aggregate Awareness Etc - based on the Business scenario these can be used 36i have some queries that I have one project in business objects, like computer  peripheral(nrps) for sales, in that I have face question like what is the main objectives of ur  projects 32. What is an alias? 

Aliases are references to existing tables in a schema. An Alias is a table that is An exact duplicate of the original table (base table), with a different name. The Data in the table is exactly the same as the original table, but the different name "Tricks" the SQL of a query to accept that you are using two different tables.

33. How we drill up week to Month? 

In data Warehouse when u change + symbol to - , u would c all the aggregation level in that + this is called rolling down. So if u again click over that - it would again compressed back to +. This is call drill up. Your Aggregation levels would b like

Year>Month>Week>Day>Hour>Minutes>Seconds. So by changing the symbol from - to + at month aggregation level u can drill up.

34. What is a join? Explain different types of joins? 

Join is used to link to tables depending upon the data requested by the user, Usually we have Inner Join, Outer Join, Left Join, Right Join, Full Outer join. 35. What’s universal join in BOs? 

The level of join between two universes with a matching column 36. What is a join? Explain different types of joins? 

Join is used to link to tables depending upon the data requested by the user, Usually we have Inner Join, Outer Join, Left Join, Right Join, Full Outer join. 37. What is a join? Explain different types of joins? 

Join is used to link to tables depending upon the data requested by the user, Usually we have Inner Join, Outer Join, Left Join, Right Join, Full Outer join. -

38. How achieve the many to many relation ship in Busi...

A) If you have two tables with many to many relation ships, take the keys of those tables and form a 1-1 relationship table. Then you can connect both the existing tables to the newly formed table using the key. B) Create an intermediate table with 2 keys. i.e., the primary keys of both tables. Join each table to its primary key in the intermediate table.

C) m to m relation ship m to 1 1 to m This way you can join 39. What is the difference between condition & filter? 

A) Condition allows us to limit the data displayed from the database and Filter allows us to hide the data which is already generated in the report. B) Conditions: these retrievals the data based on the condition (universe level) Filter: it brings the data and filter; performance will be slow (report level) C) Condition allows us to limit the data displayed from the database and Filter allows us to hide the data which is already generated in the report.

D) A Condition feature that forces a query to retrieve only the data that meets specified criteria. Condition is placed on a report query to show the specific data. To define a condition Name, Description and Where clause are required A Filter enables you to view only necessary data in a report .i.e. it allows you to restrict the no. of rows displayed in the report they affect only the data currently displayed in the block but not query results Ex: Select values for a variable in the report to apply a simple filter 

In a report can we hide a particular object?

Yes we can show/hide a particular object in a table by using the pivot tab of the format table dialog box 40. What are Alerter, Filters, Breaks and Conditions? –

Alters are nothing but they are used to draw attention to a block of data by highlighting. Breaks are nothing but grouping the data without any change in the format. Condition is used to retrieve data which meets certain criteria. Filters are used to get necessary data. 41. How to filter repetitive values in the report to get distinct values? 

A) In the Query panel we have tab "Options” Click there to get "eliminate duplicate enable this options. Example: In any database we can use distinct command but My Report source is flat file. Therefore I can’t manipulate source system. B) Using the eliminate duplicates option is one way. In a slightly different scenario, duplicates could come up due to the design structure of the report. E.g. In some specific cases, one may want to display a value in one field (say in a folded report) but multiple values come up (which could give you a COMPUTATION ERROR). To avoid such situation, one can define a variable which would e the max of the original field required. That ways the same value is fetched and also only one value is returned. C) One other way possible is by doing "No Duplicates" radio button in the Options of the data provider in the Definition (the black cube) But sometimes in free-hand sql reports it is not possible. 42. When to use local filter and when to use global Filter? 

Think this should be in the Reporter Forum but, a local filter would apply to just a single block (table, cross tab or chart) within your report. A global filter would apply to all blocks in your report, so if you had many tables the filter  would apply to all of them Local Filter is to single report to which it is create, but a global filter is to all the reports which consists of that column

43. Is there any command or function to filter repeating records/values in the report? 

Using the eliminate duplicates option is one way. In a lightly different scenario, duplicates could come up due to the design structure of the report. E.g. in some specific cases, one may want to display a value in one field (say in a folded report) but multiple values come up (which could give you a COMPUTATION ERROR). To avoid such situation, one can define a variable which would e the max of the Original field required. That ways the same value is fetched and also only one value is returned 44. What is drill filter and its usage? How many types of filters are there? 

I don’t think there is any number of types in drill through filter, drill through filter is used to fetch the particular data from the report or other report by click browse while in the drill through process. 45. What is drill filter and its usage? How many types...

Three types of drill is in BO.1.drill up, 2.drill down, 3.drill thro'. Drill up means second->minutes->hour->->day Drill down means region->country->state->district Drill thro'--whatever u want that element Drill filters acts as query conditions when you bring new data from database We can not say there are different types of drill filters, because we apply filters through scope of analysis and set the apply drill filters option by Tools >options>drill tab There are different drill modes like drill up, drill down, drill through 46. What are the steps to do to use Alerts in BO? 

Alerts are used to alert some part of the data if any change occurs. select the part of the data in the report where u want to keep alerts n just click on alerts in the tool bar which is present in the third line from menu bar besides rank then a window pops up n we ca n give some condition where in if it crosses that an alert is sent 47. Please explain about Alerts in Bo's, under what situation we need to use alerts

Hello friends, here alert means to highlighted data in a particular report. In every report we can apply alerts situation like, sales revenue per city wise. Here city field we can apply alert, condition like sales revenue >=50,000 48. What are Alerter, Filters, Breaks and Conditions? 

Alters are nothing but they are used to draw attention to a block of data by highlighting. Breaks are nothing but grouping the data without any change in the format. Condition is used to retrieve data which meets certain criteria. Filters are used to get necessary data.

49. Can you create Alerts in WEB Intelligence? 

In Version6 we can't create alerts in WEBi but it is available in XIR2 50. Can you add the Cascading prompts in Business Objects? 

Answer: - if you select one prompt value based on that prompt value gives other low (that low value is have relate that 1st prompt value) you can sele ct one or more from that value. South (region) > TN, AP, kr, kl (state) North (region) > nd, jk, hr, up (state) If I select region south I can see only south region state. (This is cascading prompt) It should create universe level. Double click state object > Edit properties > properties > edit You can see the query pan, there pull down that region object and use that prompt conditions and save that Now you click display button you can see how that prompts are working. 51. Give the notes and functionalities of cascading prompts, @ script in business objects Syntax

@Prompt ("message", ["type"], [lov], [MONO|MULTI], [FREE|CONSTRAINED])

where message is the text of a message within single quotes. Type can be one of the following: "A" for alphanumeric, "N" for number, or "D" for date. Lov can be either a list of values enclosed in brackets (each value must be within single quotes and separated by commas) or the name of a class and object separated by a backslash and within single quotes. MONO means that the prompt accepts only one value. MULTI means that the prompt can accept several values. FREE refers to free input as opposed to CONSTRAINED, which means that the end user must choose a value suggested by the prompt. Description is used to create an interactive object. In the Query Panel, this type of object causes a message to appear. This message prompts the end user to enter a specific value. Note the last four arguments are optional; however, if you omit an argument you must still enter the commas as separators. Example

In Where Clause: City. City IN @Prompt ("Choose City", "A", {"Chicago", "Boston", "New York"}, MULTI, FREE) In the Query Panel, the object prompts the end user to choose a city. 52. What is Nested prompt and how to create this prompt? 

Nested prompts are called "Cascading Prompts" in Business Objects environment. Try searching for this keyword. To create cascading prompts, you need to edit the properties of  an object & impose another prompt as a condition. 53. What is a Universe? 

A) It is a semantic layer between Database and the designer used to create objects and classes. (It maps to data in Database). 54. How do you design a universe? 

The design method consists of two major phases. During the first phase, you create the underlying database structure of your universe. This structure includes the tables and columns of a database and the joins by which they are linked. You may need to resolve loops which occur in the joins using aliases or contexts. You can conclude this phase by testing the integrity of the overall structure. During the second phase, you can proceed to enhance the components of your universe. You can also prepare certain objects for multidimensional analysis. As with the first phase, you should test the integrity of your universe structure. You may also wish to perform tests on the universes you create from the Business Objects User module. Finally, you can distribute your universes to users by exporting them to the repository or via your file system. For a universe based on a simple relational schema, Designer provides Quick Design, a wizard for creating a basic yet complete universe. You can use the resulting universe immediately, or you can modify the objects and create complex new ones. In this way, you can gradually refine the quality and structure of your universe 55. What are Linked Universes? 

If the data provided is from two different data providers then we can link those two universes, such type of universe is called Linked Universe. 56. In the BO universe, how to link two universe, like I have one universe in sales.uni and  another is marketing.uni 

In BO Designer, from File Menu -> Parameters -> Links tab on Universe Parameters box. Click Add link to link the universe. The linking universe should be exported and imported from repository before linkin g. 57. Types of universes in business objects? 

Simple and Complex.

58. How can you check the universe? 

By making use of Check integrity button 59. What are the user requirements in a universe? 

Database connections, key column, join and check for loop if you need measures, metrics, 60. How can you check the integrity? 

By making use of Check integrity button. 61. What are Universe parameters? 

Name of the universe, description and RDBMS connection, size and rights. 62. How can we improve performance? 

By making use of Aggregate tables. 63. How many universes can be created in a project 

We can create any number of universes, but at a time we can open only one universe, generally number of universes should be equal to number of sub-domains. 64. In the BO universe, how to link two universe, like I have one universe in sales. uni and  another is marketing.uni 

In BO Designer, from File Menu -> Parameters -> Links tab on Universe Parameters box. Click Add link to link the universe. The linking universe should be exported and imported from repository before linking. 65. What are the user requirements in a universe? 

Database connections, key column, joins and check for loopif you need mesures, metrics, cheers,www.sithu.s5.com 66. What are Universe parameters? –

Name of the universe, description and RDBMS connection, size and rights. 67. what all will be exported to the repository, when we export a universe ? 

When we export a universe first time, a unique identifier is allocated to the universe and this identifier is updated on the local version of the universe in the universe domain. If we export the universe to a diff, domain and now the universe has an identifier for diffdomain (EX: exporting a universe from a development domain to a production domain) when a designer exports the universe to the Repository (universe domain) they must export all the related LOV files (which contains the data values associated with an object) to the document domain. 68. How many universes can be created in a project...? 

 In a project you can create multiple universes. For multiple universe usage linked universe is an ideal concept.

69. What is the size of data base? 

In general it will be anything between 4-8 Terabytes. 70. Dimension Parameters for analysis. Dimensions typically relate to a

Hierarchy such as geography, product, or time. For example Last Name and CityId 71. What is a Fact Table

A fact table contains statistical information about transactions. For example, it May contain figures such as Sales Revenue or Profit. 72. What is an aggregate table? 

These are tables that contain pre calculated data 73. What is a Lookup Table? 

A lookup (or dimension) table contains information associated with a particular  Entity or subject. 74. Classes

A class is a logical grouping of objects within a universe. It represents a category Of objects. The name of a class should indicate the category of the objects that it Contains. A class can be divided hierarchically into subclasses. 75. When is the Repository created? 

- In 5i/6i versions after installing the software, whereas in Xi version a repository is created at the time of installation. 76. Question when we use aggergate awarness function in designer? 

1. In order to solve fan trap in business objects we either create alias table or aggregate awareness function 2. Through aggregate navigation we can also select the compatible as well as incompatible objects Ex:-year, quarter, month, week, day Year:-quarter, month, week, and day are compatible objects Quarter:-year class is incompatible and month, week, days are compatible. 3. We specify the objects in descending order  77. What is difference between custom hierarchy and report based hierarchy? 

By default one class having one hierarchy i.e. called report hierarchy. Custom hierarchy we can create in designer according our req.

78. Clearly explain the difference between union and group

The difference between union and group is as follows: take two tables t1 and t2.in t1 we have columns like a,b,c,d. and t2 has a,d,e,f.so union means t1 union t2 i.e. getting result from both tables i.e. a,b,c,d,e.,f  where as group performs on a individual column in a particular table. 79. What is difference between custom hierarchy and report based hierarchy? 

By default one class having one hierarchy i.e. called report hierarchy. Custom hierarchy we can create in designer according our req. 80. Explain the difference between union and group

Take two tables t1 and t2.in t1 we have columns like a, b, c, d. and t2 has a, d, e, f .so union means t1 union t2 i.e. getting result from both tables i.e. a, b, c, d, e, f where as group performs on a individual column in a particular table. 81. How to generate the report from excel sheet? 

Start BO, Select "Others" on Data Providers wizard page, From drop down menu, select "personal data files", Specify file location & check the box "First Row contains Column names" this will help you in creating Objects. Click Ok. Start building your reports....... 82. What is the difference between slice and dice & drill through

Slice and dice allows us to show and hide the objects Where as drill allows us to drill the data like drill up, drill down, drill through depending upon the user requirements. 83. What is the difference between slice and dice and cross tab report? 

Slice and Dice: Arrangement of Data Crosstab report is for Comparison.

84. What is the difference between tabular report& cross tab report? 

Answer: - Tabular reports are a 2D format and Cross tab reports is a 3D format. Most of the operational/formatted reports will be created in tabular form and most of the analytical reports are created in the cross tab report form (Product VS Year VS Sales amount)

85. How to schedule the report in B.O? 

We can schedule the reports through broadcast agent. 86. What is the use of BCA? 

BCA is used to refresh and schedule and export and save as.html, .rtf, .xls, .PDF. We should use Detect Aliases and Detect Contexts to formally identify and resolve loops. I.e. if a loop contains only one lookup table then the loop can be resolved by detecting the alias. If a loop is having 2 or more fact tables (multiple fact tables) then the loop can be resolved by detecting context. http://www.newinterviewquestions.com/cat/Business-Objects-interview-questions/

87. How to schedule the report in B.O? 

We can schedule the reports through broadcast agent. 88. What is the use of BO SDK? 

–

Bo SDK main use is to suppress “no data to fetch” using Macros BO SDK is a software development kit. 89. What is BO Main Key? 

Bo Main Key file contains the information about the repository site i.e. it contains the address of the repository security domain. 90. What are the general issues in migration process? 

Alignment, performance. 91. What is REPORT BURSTING and how to do it in BCA as I have to split the report and  send diff reports to diff people

If some part of the data in your report is sensitive, you can't risk sending the whole report to everybody, even to those who need to see the least sensitive part of report! Solution is Report Bursting. You can send reports to BCA for scheduled processing & distribution to users based on THEIR profiles (profile = user rights) & not based on your  profile! BO 5 & WebI 2.5 procedure to do this: Open the document; click "Send to Broadcast Agent" on Doc Exchange toolbar. In Actions tab select "Refresh with the Profile of Each Recipient" In the Distributions tab select "Distribute via the Business Objects Repository. (Only option to enable you for Report Bursting)

Click To, select recipients, Schedule it & OK. In WebI 2.5...........

In Refresh options Select Scheduled Refresh & click send On Scheduling Options, Set "Refresh According to the profile of each recipient" to Yes & OK.

92. Can someone please let me know the things we can do in WEBi and cannot do it in FULL CLIENT and vice versa for BO6.5 

We can create\edit Universe in the full client but not in WebI 2) WebI has comparatively less functions to use than in Full client 3) In Full Client we can write macros\addins but I am not sure whether we can do the same in WebI or not. Please revert back if these are wrong 93. What we can do in WebI and cannot do it in FULL CLIENT and vice versa for BO6.5 

We can create\edit Universe in the full client but not in WebI 2) WebI has comparatively less functions to use than in Full client 3) In Full Client we can write macros\ad dins but I am not sure whether we can do the same in WebI or not. 94. Difference between ZABO and Webi 

ZABO is zero administrator businessobjects , which will be installed on your local m/c when any full client report in opened/edited from infoview . For this you don’t require any BO mainkey , key will be installed from BO server.Webi is also called as thin client , where -in you are create BO reports on web browser . Reports are only based on Universe . Both are user in 3-trier architecture. ZABO-Zero Administration BusinessObject means we don’t need to install BO to view the reports. while we open the reports through infoview the server installs the required components to your local machine. We don’t need any bomain key etc. WebI is a web based application in BO. We will create web based reports in WebI(it’s a  java based application). We can publish reports to personal & corporate by WebI and can save as pdf file. 95. How many ways we test the universe & Report? 

By doing integrity check we can test universe & By coping report query and run in backend(oracle,sql server...) we can test the data by comparing both. 96. How do we test the reports in the business objects...

In the central management consol one can test the report.

97. How do we test the reports in the business objects? How to create the tabs in the reports? 

In the central management consol one can test the report. Just go to the link http://ipadress:port no/businessobjects/enterprise11/admin/en/admin.cwr .every thing can check from the Bo. 98. How can we do load testing for WebI Reports? (Example if I have to test one WebI report  for Concurrent users refreshing report at one time

You can do Load testing for WebI Reports using Load runner tool. 1) Install load runner in your system. (To use load runner you need admin rights). 2) Generate load runner scripts. 3) Use controller (which is present in load runner) to get the results. Using load runner tool you will get these results: a) Maximum Running Users: 50 (Given by the testing person, you can increase virtual users if you want) b) Hits per second. c) Average response time for every transaction like login, click on the particular link, logout etc., d) Errors per second. e) Connections per second

99. How to break a Date field into Year, month, week, and day?(For example: I have a field  INVOICE_DATE. Now I want to break it as Year, month..... I.e. in time dimension.) DO I need  to have some changes in Universe? 

Create objects in your universe with date functions. Let's say your DB is Oracle. In your "Select" statement of new object called year, try to_char(INVOICE_DATE, 'YYYY') similarly for month create object called month & repeat process, simply replace'YYYY' with 'MM' of 'MMM' in the select statement. & so on. 100. Can someone please give some information on REPORT BURSTING and how to do it in BCA as I have to split the report and send diff reports to diff people

If some part of the data in your report is sensitive, you can't risk sending the whole report to everybody, even to those who need to see the least sensitive part of report ! Solution is Report Bursting.

You can send reports to BCA for scheduled processing & distribution to users based on THEIR profiles (profile = user rights) & not based on your profile ! BO 5 & WebI 2.5 procedure to do this : 1. Open the document, click "Send to BroadCast Agent" on Doc Exchange toolbar. 2. In Actions tab select "Refresh with the Profile of Each Recipient" 3. In the Distributions tab select "Distribute via the Business Objects Repository. (only option to enable you for Report Bursting) 4. click To, select recipients, 5. Schedule it & OK.

In WebI 2.5........... In Refresh options Select Scheduled Refresh & click send On Scheduling Options, Set "Refresh According to the profile of each recipient" to Yes & OK. 101. How Do U Create Report in BO, if given fixed length file ( Notepad) as source? 

To create a report using notepad (.txt files) : 1.Open BusinessObjects --> new report 2. Select data provider as others in stead of universe, • • •

•

from "Others" drop down list, select "Personal Data Files", File selection box appears, specify the location of your text file, if you have separated data by tabs in text file select "Tabulation" if by comma then "Comma Separated" (I don’t remember the exact caption for this option) & if space separated then sele ct "Characters"(I don’t remember the exact caption for this option) if you have specified column names in your text file, check the box "First Row contains Column names"

Run the report. 102. How to execute the plsql procedure from the report by clicking with mouse

We can select either tables or procedures or views as our data to generate our reports. In the designer in bo's we can select tab "insert" n select the particular data source for generating the report through mouse click. 103.

What is a derived table in data warehousing 

Derived tables are not real tables at the Database level , but are the selection of few columns in the Table with some aggregations, specific to the report. This feature is available in BO 6.5 and later versions. Sel a1,a2,a3,max(a4)

From a , (Sel b1, b2, max(b3) as B3, Min(B4) as B4 from B group by b1,b2) as BX where BX.B1= a.a1 group by a1,a2,a3 order by a1,a2,a3 The (Sel b1, b2, max(b3) as B3, Min(B4) as B4 from B group by b1,b2)Â in the above query is a derived table. The same definition has to be added in the Universe - by going into Insert >> Derived Tables. Type the Query - parse it and the new table inserted can be used to any type of join / Contexts etc in the Universe. 104. What is report template in B.O? 

Report Template is a specimen for your future reports. You create a report from scratch, say make it Master-Detail Report with charts, put your company logo, add some default colors(something like same colors your company uses for its documents, WebPages etc.) & then save it as BO Report Template file. Next time when you are creating new reports, & select use Templates option, your report saved as template will be listed in the box. If you select it, your new report will automatically use all color formats, & table-chart structures, logo....whatever you used in your template report file. Advantage : 1 time development of display & structure format, for multiple reports use. I.e. Time Saving. No need of formatting for all standard reports Definition of ERP (Enterprise Resource Planning) Enterprise resource planning (ERP) is the industry term used to describe a broad set of activities supported by multi-module application software that helps a manufacturer or other business manage the important parts of its business. These parts can include product planning, parts purchasing, maintaining inventories, interacting with suppliers, providing customer service, and tracking orders. ERP can also include application modules for the finance and human resources aspects of a business. Definition of Etl (extract, transform, load) Short for extract, transform, load, three database functions that are combined into one tool to pull data out of  one database and place it into another database. Extract -- the process of reading data from a database. Transform -- the process of converting the extracted data from its p revious form into the form it needs to be in so that it can be placed into another database. Transformation occurs by using rules or lookup tables or by combining the data with other data. Load -- the process of writing the data into the target database.

http://www.computerworld.com/databasetopics/businessintelligence/datawarehouse/story/0,10801,89534,00. html What is OLAP? Short for Online Analytical Processing, a category of software tools that provides analysis of data stored in a database. OLAP tools enable users to analyze different dimensions of multidimensional data. For example, it provides time series and trend analysis views. OLAP often is used in data mining. Functionalities

Before we speak about OLAP tool selection criterion, we must first distinguish between the two types of OLAP tools, MOLAP (Multidimensional OLAP) and ROLAP (Relational OLAP). 1. MOLAP: In this type of OLAP, a cube is aggregated from the relational data source (data warehouse).

When user generates a report request, the MOLAP tool can generate the create quickly because all data is already pre-aggregated within the cube. 2. ROLAP: In this type of OLAP, instead of pre-aggregating everything into a cube, the ROLAP engine

essentially acts as a smart SQL generator. The ROLAP tool typically comes with a 'Designer' piece, where the data warehouse administrator can specify the relationship between The relational tables, as well as how dimensions, attributes, and hierarchies map to the underlying database tables. Right now, there is a convergence between the traditional ROLAP and MOLAP vendors. ROLAP vendor  recognize that users want their reports fast, so they a re implementing MOLAP functionalities in their tools; MOLAP vendors recognize that many times it is necessary to drill down to the most detail level information, levels where the traditional cubes do not get to for performance and size reasons. So what are the criteria for evaluating OLAP vendors? Here they are:

Ability to leverage parallelism supplied by RDBMS and hardware: This would greatly increase the tool's performance, and help loading the data into the cubes as quickly as possible. Performance: In addition to leveraging parallelism, the tool itself should be quick both in terms of loading the data into the cube and reading the data from the cube. Customization efforts: More and more, OLAP tools are used as an advanced reporting tool. This is because in many cases, especially for ROLAP implementations, OLAP tools often can be used as a reporting tool. In such cases, the ease of front-end customization becomes an important factor in the tool selection process. Security Features: Because OLAP tools are geared towards a number of users, making sure people see only what they are supposed to see is important. By and large, all established OLAP tools have a security layer that can interact with the co mmon corporate login protocols. There are, however, cases where large corporations have developed their own user authentication mechanism and have a "single sign-on" policy. For  these cases, having a seamless integration between the tool and the in-house authentication can require some work. I would recommend that you have the tool vendor team come in and make sure that the two are compatible. Metadata support: Because OLAP tools aggregates the data into the cube and sometimes serves as the front-end tool, it is essential that it works with the metadata strategy/tool you have selected. 

105. Objects infer SQL structures displayed in a schema

The objects that Business Objects and Web Intelligence users see in a universe Infer SQL structures that you have inserted into a database schema. You, as the Universe designer, create this schema based on the tables and joins that are Required to return the data, needed by users for their analysis and report creation. Object type Description 106. What is BO Main Key? 

Bo Main Key file contains the information about the repository site i.e. it contains the address of the repository security domain. 107. What is metrics? –

Metrics are a system of parameters or ways of quantitative and periodic assessment of a process that is to be measured; these are used to track trends, productivity. 108. Why do we need metrics and sets? 

- Metrics are used for analysis and Sets are used for grouping. 109. What is a Set? 

Its nothing but grouping of users. 110. What is the use of AFD? Where it can be stored? 

Used to create dashboards. It can be stored in repository, corporate or personal.

111. What is the source for metrics? 

Measure objects. 112. Is there any bug in 6.x? 

In earlier version of 6.0 they had, but 6.5 is the best version with out any bugs. 113. Analysis in BO? 

Slice-Dice and Drill analysis. 114.  Are Data mart and DWH normalized or demoralized ? Do both of them exist in The same tier ? 

Yes both can exist on the same tier because Datamart is a subset of data warehouse and it supports a particular region, business unit or business function. The data in the Datamart and DWH is Denormalized and optimized for OLAP systems. 115. What is a Data Cube ? What is its use ? 

Data cube will present in BO tool. Data cube is used for storing the data values which we are using in the documents. We can clear the data cube by using purge command. Data provider is used to retrived the datas from data cube to documents. Data cube is the representation of data along every possible dimension included in the query. Data cubes are processing units composed of fact and dimensions. 116.  Are Data mart and DWH normalized or demoralized ?...

Yes both can exist on the same tier because Datamart is a subset of data warehouse and it supports a particular region, business unit or business function. The data in the Data mart and DWH is Demoralized and optimized for OLAP systems 117. Can we apply Rank and Sort at a time on a single report? 

No we can’t apply rank and sort at a time on one object in one single report. If we try to apply, BO asks if you want to over write the previous condition. http://www.geekinterview.com/Interview-Questions/Business-Objects/page9

. 118. What is Thumbnail? 

Business Objects Enterprise lets you preview a report using thumbnails. You can request the server to take a snapshot of the first page of the report and return it to the browser as an image file. This image can then be displayed as part of the Report Details page.

To retrieve a thumbnail, a separate page needs to be created because the code that writes an image to the screen erases any text that may have previously been there. 119. What is the dense rank? 

The DENSE_RANK function computes the rank of a row in an ordered group of rows. The ranks are consecutive integers beginning with 1. The largest rank value is the number of  unique values returned by the query. Rank values are not skipped in the event of ties. Rows with equal values for the ranking criteria receive the same rank. The DENSE_RANK function does not skip numbers and will assign the same number to those rows with the same value. Hence, after the result set is built in the inline view, we can simply select all of the rows with a dense rank of three or less, this gives us everyone who makes the top three salaries by department number. ex: Give me the set of sales people who make the top 3 salaries - that is, find the set of  distinct salary amounts, sort them, take the largest three, and give me everyone who makes one of those values. SELECT * FROM ( SELECT deptno, ename, sal, DENSE_RANK() OVER ( PARTITION BY deptno ORDER BY sal desc ) TopN FROM emp ) WHERE TopN nd, jk, hr, up (state) If I select region south I can see only south region state. (This is cascading prompt)

It should create universe level. Double click state object > Edit properties > properties > edit You can see the query pan, there pull down that region object and use that prompt conditions and save that Now you click display button you can see how that prompts are working. 128. What is a derived table in data warehousing 

Derived tables are not real tables at the Database level, but are the selection of few columns in the Table with some aggregations, specific to the report. This feature is available in BO 6.5 and later versions. Sel a1, a2, a3, max (a4) From a , (Sel b1, b2, max (b3) as B3, Min (B4) as B4 from B group by b1, b2) as BX where BX.B1= a.a1 group by a1,a2,a3 order by a1,a2,a3 The (Sel b1, b2, max(b3) as B3, Min(B4) as B4 from B group by b1,b2)Â in the above query is a derived table. The same definition has to be added in the Universe - by going into Insert >> Derived Tables. Type the Query - parse it and the new table inserted can be used to any type of join / Contexts etc in the Universe. 129. What is the difference between tabular report& cross tab report ? 

Tabular reports are a 2D format and Cross tab reports is a 3D format. Most of the operational/formatted reports will be created in tabular form and most of the analytical reports are created in the cross tab report form (Product VS Year VS Sales amount) 130. Can we apply Rank and Sort at a time on a single report 

No we can’t apply rank and sort at a time on one object in one single report. If we try to apply , BO asks if you want to over write the previous condition.

131. Which versions are used in the BO dashboard work? 

Latest version

132. I have some queries that I have one project in bussiness objects, like computer   peripheral(nrps) for sales, in that I have face question like what is the main objectives of ur   projects

Answer Your objectives for this project will be your Report Requirements. whatever the requirements are baselined, you will develop the universes & create simple, complex reports. Requirements can be : Standard sales reports -- Location wise, product line /category wise etc.Complex Reports -- some reports using multi-data providers, report level variables & using report enhancements with the help of SDKs(.NET /JAVA)Ad-Hoc Reports -- Misc. reports which end users can create using your universes & are not the part of your Standard Reports.& Overall Objective will be -----------------Empowering the Key Decision Makers with historical Information in accurate, consistant,analytical format of flexible Reports (reports that can be sliced & diced as per requirements) for accurate & predictive Strategic Decision making. 133. How to select different data providers in business objects? 

Answer Once you have your report generated, right click in the left window (your variables) click on "New Data Provider" follow the wizard. & you are done.If trying to use diff. data provider for different reports, after creating 1 report, right click on the Report1 tab located at the bottom, click insert new then the procedure is same to add data provider. 134. What is a derived table in data warehousing? 

Answer it is similar to views, it is mainly used to restrict the datas

135. What is Business objects Repository? –

it is nothing but metadata. 136. What is domain? How many are there in a basic setup? What are they? 

Domain is nothing but logical grouping of system tables, There are three domains usually in a basic setup, and They are Secure, Universe, and Document. Business objects are sometimes called domain objects (where the word domain means the business), and a domain model represents the set of domain objects and the relationships between them. 137. Can we have multiple domains?  - Yes.

(Security domain can not be multiple).

138. How do you restrict access to rows of a database? 

- In XI version it can be done by using row-level security in designer module whereas in 5i/6i it is done by supervisor. 139. What is a category? 

It is nothing but grouping of certain entities. 140. How can we improve performance? 

By making use of Aggregate tables. Analysis in BO? –

Slice-Dice and Drill analysis. .

141. clearly explain the difference between union and group

The difference between union and group is as follows: take two tables t1 and t2.in t1 we have columns like a,b,c,d. and t2 has a,d,e,f.so union means t1 union t2 i.e. getting result from both tables i.e. a,b,c,d,e.,f  where as group performs on a individual column in a particular table. 142.  Are Data mart and DWH normalized or demoralized ? Do both of them exist in the same tier ? 

Yes both can exist on the same tier because Datamart is a subset of data warehouse and it supports a particular region, business unit or business function. The data in the Datamart and DWH is Denormalized and optimized for OLAP systems.

143. What is a Data Cube ? What is its use ? 

Data cube will present in BO tool. Data cube is used for storing the data values which we are using in the documents. We can clear the data cube by using purge command. Data provider is used to retrived the datas from data cube to documents.

144. Can we apply Rank and Sort at a time on a single report 

No we can’t apply rank and sort at a time on one object in one single report. If we try to apply , BO asks if you want to over write the previous condition.

146. How to break a Date field into Year, month, week, and day?  (For example: I have a field INVOICE_DATE. Now I want to break it as Year, month..... I.e. in time dimension.) DO I need to have some changes in Universe? 

Create objects in your universe with date functions. Let's say your DB is Oracle. In your "Select" statement of new object called year, try to_char(INVOICE_DATE, 'YYYY') similarly for month create object called month & repeat process, simply replace'YYYY' with 'MM' of 'MMM' in the select statement. & so on. 26List of charts and graphs we can generate in Business Objects, with some supporting document (any supporting link or PDF file as it is to be sent to client)?

40.

147. What is domain? How many are there in a basic setup? What are they? 

Domain is nothing but logical grouping of system tables, there are three domains usually in a basic setup, and they are Secure, Universe, and Document. Business objects are sometimes called domain objects (where the word domain means the business), and a domain model represents the set of domain objects and the relationships between them. 148. When is the Repository created? 

In 5i/6i versions after installing the software, whereas in Xi version a repository is created at the time of installation. 149. Can we have multiple domains? 

Yes. (Security domain can not be multiple). 150. How do you restrict access to rows of a database? 

In XI version it can be done by using row-level security in designer module whereas in 5i/6i it is done by supervisor. 151. What is difference between custom hierarchy and report based hierarchy? 

By default one class having one hierarchy i.e. called report hierarchy. Custom hierarchy we can create in designer according our req. 152. Can we apply Rank and Sort at a time on a single report? 

No we can’t apply rank and sort at a time on one object in one single report. If we try to apply, BO asks if you want to over write the previous condition. 153. What is meant by Object Stores? 

Answer Object store is nothing but the container of object which is created after rpt file run once.

154. What we can do in WebI and cannot do it in FULL CLIENT and vice versa for BO6.5 

We can create\edit Universe in the full client but not in WebI 2) WebI has comparatively less functions to use than in Full client 3) In Full Client we can write macros\ad dins but I am not sure whether we can do the same in WebI or not. 155. Can a universe be connected to different databases...

A)NO a universe can not take the data from more that one database ,if ever we want data from another database we have to create another universe or use different data provider  while report creation B)yes, a universe can be connected to different database. However to do so, we have to link two universes which are on different database. however if we consider, unlink universe(or only one universe), then it is not possible to have a universe that is connected to different database as in a universe we have only one connection at a time. C)NO. A universe cannot connect to more than one database at the same time. But in Report we can use multiple data providers which internally two different universe and 2 different database. D)Yes, You can do using multiple data providers 156. How Do U Create Report in BO, if given fixed length file (Notepad) as source? 

1. Open Business Objects --> new report select data provider as Others instead of universe, from "Others" drop down list, select "Personal Data Files", File selection box appears, specify the location of your text file, if you have separated data by tabs in text file select "Tabulation" if by comma then "Comma Separated" (I don’t remember the exact caption for this option) & if space separated then select "Characters"(I don’t remember the exact caption for this option) if you have specified column names in your text file, check the box "First Row contains Column names" Run the report 157. How to select different data providers in business objects? 

Once you have your report generated, right click in the left window (your variables) click on "New Data Provider" follow the wizard. & you are done. If trying to use diff. data provider for  different reports, after creating 1 report, right click on the Report1 tab located at the bottom, click insert new then the procedure is same to add data provider. 158. How to execute the plsql procedure from the report by clicking with mouse

We can select either tables or procedures or views as our data to generate our reports. In the designer in Bo we can select tab "insert" n select the particular data source for  generating the report through mouse click.

159. How to generate the report from excel sheet? 

Start BO, Select "Others" on Data Providers wizard page, From drop down menu, select "Personal data files", Specify file location & check the box "First Row contains Column names" this will help you in creating Objects. Click Ok. Start building your reports....... 160. what is the difference between slice and dice & drill through

Slice and dice allows us to show and hide the objects Where as drill allows us to drill the data like drill up, drill down, drill through depending upon the user requirements. 161. what is a derived table in data warehousing 

Derived tables are not real tables at the Database level, but are the selection of few columns in the Table with some aggregations, specific to the report. This feature is available in BO 6.5 and later versions. Sel a1, a2, a3, max (a4) From a , (Sel b1, b2, max (b3) as B3, Min (B4) as B4 from B group by b1, b2) as BX where BX.B1= a.a1 group by a1,a2,a3 order by a1,a2,a3 The (Sel b1, b2, max(b3) as B3, Min(B4) as B4 from B group by b1,b2)Â in the above query is a derived table. The same definition has to be added in the Universe - by going into Insert >> Derived Tables. Type the Query - parse it and the new table inserted can be used to any type of join / Contexts etc in the Universe. 162. What is the difference between master-detail and Breaks? 

In break common fields are deleted (here in this case the table format is not changed) whereas in master-detail , we declare certain entity as a master to get the detailed information or report in this case the table format is changed. 163. What is the difference between break and section I...

The major difference between these 2 are It breaks up the data in a table or crosstab by grouping the data according to a selected value and it allows you to display all the data for each value of a dimension variable

together mainly it displays SUBTOTALS. COLUMN BREAK's are used to avoid the repetitive value occurrences Section is obtained in the Master/detail reports which enable you to split large blocks of  data into sections. This type of presentation allows you to minimize repeating values and to display subtotals. 164. What is the difference between break and section I...

Here is the difference Ex: Creating a Break and a Section When you create a break on Year, the data remains as one block. The year values are repeated for each corresponding value of State and Sales Revenue. When you create a section on Year, the data is no longer contained in one block, but divided into sections. One section for each value of Year. Each section is a separate block 165. What are the requirements for cube creation in bus...

You should have a "Universe" with proper star or snowflake schema(Dimension and Fact) .Call this Universe in the "infoview" to create a web intelligent analysis(OLAP) report. 166. Business objects is which type of the OLAP Tool? 

BO is ROLAP Tool The functionality and feature sets are significantly different and so are the costs. Generally speaking, BI tools are categorized by a) their architecture (i.e., ROLAP, MOLAP, HOLAP, DOLAP, etc.) and b) their cost (i.e., high end or low end) which is usually related to the size of their feature set. For example, DOLAP solutions would include Cognos and Crystal, MOLAP solutions would include Essbase, SAS and Oracle Express, ROLAP solutions would include Business Objects, Informatica and Microstrategy and so on. Similarly, Cognos, Brio, Crystal and Microsoft OLAP are considered low-end solutions, while Business Objects, Microstrategy, Essbase and Informatica are considered high- end solutions. 167. How does the hierarchy and scope of analysis help...

Hierarchy is about the levelsorder of the objects in the classes. E.g. Time hierarchy in a time class will be Year, Quarter, Month, Week, Day, Hour, Minute, Second By defining a scope of analysis during drilling you are specifying up to what level in the hierarchy you want to drill. if you set scope of analysis as 2, the data will be drilled to Year, quarter. 3 will include month as well as so on. 168. How do you Find the average of an object with out using the Average Function and by  using only sum,average,max,min? 

Use Sum() and Count() function like Sum() / Count() you will get your average value.

169. What is difference between datamart and datawarehou...

Data marts, simply defined, are smaller data warehouses that can function independently or can be interconnected to form a global integrated data warehouse 170. How many tabs can be added in a report i.e. how ma...

It depends on the hierarchy of the class.. but still w can define in slice and dice panel.. that is up to 2 times or 3 times... like that 171. What is the maximum limit of the data providers in...

There does not seem to be any limit however the documents say that you can have maximum of 15, but I have seen close to 50 dataproviders in a report. 172. How do you check whether the data in the rep...

We can copy the SQL Generated in the Query panel and run that SQL in the Database. 173. Clearly explain the difference between union and group

A)The difference between union and group is as follows: take two tables t1 and t2. in t1 we have columns like a,b,c,d. and t2 has a,d,e,f. so union means t1 union t2 i.e. getting result from both tables i.e. a,b,c,d,e.,f  where as group performs on a individual column in a particular table. August 12, 2006 08:16:20 #2 Venkatachalam Member Since: Visitor Total Comments: N/A Clearly explain the group with one example B)If a table has 2 columns Gender and Name Gender Male Male Male Female Female

Name Tom James Harry Jenny Fern

Tom, James and Harry belong to Group Male. C)union operation can be performed on basic cubes, remote cubes, ods objects, master  data objects,infosets. i.e. u can form union operation simultaneously on cubes, ods, master  data objects, infosets. Multi provider does union operation.union operation can be performed on multi dimensional objects.

But join operation is performed only on master data objects and Ods objects which are 2 dimensional. Infosets perform join operation. 174. State the difference between WebI and Infoview 

A)In infoview you can create a WebI documents i.e. wid documents, you can open, schedule, save it as an excel or pdf or business objects document(.rep). WebI is a part of Infoview B)Infoview is the portal to the BO's business intelligence solution and infoview also allows the third party documents and It contains document lists that give an instant overview of all the documents generated from corporate data storage and made availabe to users C)Web Intelligence is a leading web-based query,analysis and reporting tool and this provides a thin-client interface for powerful adhoc queries and simple analysis. It allows users to access, analyze and share corporate data over intranet, extranets for both RDBMS dbs and OLAP servers D)WebIntelligence is the 'thin-client' (or server version) of Business Objects Reporter. It is used to create report documents. It does not reside on the users computer, but on a server. InfoView is what the user logs into, sees, and uses in their Internet Browser that allows the user to access and create Business Objects reports via the web without having to install the 'Full (or 'Thick') client Business Objects Reporter on their computer. The user can only get to WebI through InfoView. It does not reside on the users computer, but on a server. 175. What is the difference between detect alias and de...

we should use Detect Aliases and Detect Contexts to formally identify and resolve loops. i.e. if a loop contains only one lookup table then the loop can be resolved by detecting the alias if a loop is having 2 or more fact tables(multiple fact tables) then the loop can be resolved by detecting context 176. What is all difference between business objects 6...

I have found some differences b/w BO and XI and only the last is specific to XIR2 Difference between BO and XI BO uses classic BO Architecture and XI uses crystal classic Architecture BO uses 57 tables for BO repo and 8 tables for auditor where as XI uses 8 tables for CMS and 6 tables for auditor  BO has different security domains where as XI doesn’t has no different security domains BO, all objects are stored in repository where as in XI Objects are physically stored in Input FRS and instances in output FRS In BO after installing we have configure, create BO mainkey where as in XI it is install and start working

In BO classic key is an xml file and it has to be placed in relevant location where as in XI a key code is there In BO if you want to save a report to repository you have to publish that report where as in XI if you click save as and select Enterprise IN BO, BCA and supervision are entirely separate but in XI there are merged into CMC IN XI there is no separate auditor is there but there is an auditor database where we can create tables based on that BO has its own reporting tools where as XI uses crystal reports as its reporting tool BO is user centric – means rights are assigned to user where as XI is object centric – means rights are assigned on objects level not user level BO – all reports are stored in categories, in XI infoview there is folder and categor ies but all main storage is in folders In XI R1 there was no concept of full client but that concept is introduced in XI R2 177. Kindly number what are the steps to be taken to schedule the report? 

You can schedule any report using Business Objects (reporter) .1) Open report in BO2) Select option “File->Send to- BCA"3) Select the BCA name to which report has to be scheduled4) Set other options for report scheduling like time, any macro, user etc. 178. What is aggregate awareness and how can we use it? 

Aggregate awareness function is used to aggregate the values present in the classes in descending order. For instance we have year, quarter, month, week tables Then we sum the year, sum (quarter), sum (month), sum (week) in descending order  respectively. We also select the compatible as well as incompatible objects through aggregate navigation so that it improves the performance of the system in generating the report. 179. RE: What is aggregate awareness and how can we use it? 

You can use features in Designer to allow you to define the Select statement for an object to run a query against aggregate tables in the database instead of the base tables. You can set conditions so that a query will be run against aggregate tables when it optimizes the query, and if not, then the query will be run against the base tables. This ability of an object to use aggregate tables to optimize a query is called aggregate awareness. 180. What if a Cartesian product pop up block appears w...? 

Cartesian product is getting incorrect results. for instance if we have a chasm trap or a fan trap n we don’t solve them after checking the integrity also we get duplicate results of the same record i.e. nothing but Cartesian product. Ex:-we have customer, orders, and loans classes

orders for one product if the product_price is 150$ it will appear twice in the report due to traps becoz of the Cartesian product that’s why to solve the chasm trap we create context and in order to solve fan trap we create alias table. 181. What is report template in B.O? 

Report Template is a specimen for your future reports. You create a report from scratch, say make it Master-Detail Report with charts, put your  company logo, add some default colors(something like same colors your company uses for  its documents, WebPages etc.) & then save it as BO Report Template file. Next time when you are creating new reports, & select use Templates option, your report saved as template will be listed in the box. If you select it, your new report will automatically use all color formats, & table-chart structures, logo....whatever you used in your template report file. Advantage: 1 time development of display & structure format, for multiple reports use. I.e. Time Saving. No need of formatting for all standard reports. 182. How to generate the report from excel sheet? 

Start BO, Select "Others" on Data Providers wizard page, From drop down menu, select "personal data files", Specify file location & check the box "First Row contains Column names" this will help you in creating Objects. Click Ok. Start building your reports....... 183. What is a derived table in data warehousing? 

It is similar to views; it is mainly used to restrict the data 184. How to execute the plsql procedure from the report...

We can select either tables or procedures or views as our data to generate our reports. In the designer in bo's we can select tab "insert" n select the particular data source for  generating the report through mouse click. 185. How Do U Create Report in BO, if given fixed length...

To create a report using notepad (.txt files): 1. Open BusinessObjects --> new report 2. Select data provider as others instead of universe, From "Others" drop down list, select "Personal Data Files", File selection box appears; specify the location of your text file,

if you have separated data by tabs in text file select "Tabulation" if by comma then "Comma Separated" (I don’t remember the exact caption for this option) & if space separated then select "Characters"(I don’t remember the exact caption for this option) If you have specified column names in your text file, check the box "First Row contains Column names" Run the report. 186. Can someone please give some information on REPORT...? 

If some part of the data in your report is sensitive, you can't risk sending the whole report to everybody, even to those who need to see the least sensitive part of report! Solution is Report Bursting. You can send reports to BCA for scheduled processing & distribution to users based on THEIR profiles (profile = user rights) & not based on your profile! BO 5 & WebI 2.5 procedure to do this: Open the document; click "Send to BroadCast Agent" on Doc Exchange toolbar. In Actions tab select "Refresh with the Profile of Each Recipient" In the Distributions tab select "Distribute via the Business Objects Repository. (Only option to enable you for Report Bursting) Click To, select recipients, Schedule it & OK. In WebI 2.5........... In Refresh options Select Scheduled Refresh & click send On Scheduling Options, Set "Refresh According to the profile of each recipient" to Yes & OK. 187. Can someone please let me know the things we can d...

1) We can create\edit Universe in the full client but not in WebI 2) WebI has comparatively less functions to use than in Full client 3) In Full Client we can write macros\addins but I am not sure whether we can do the same in WebI or not. -In addition to those in my previous mail, 1) We can edit SQL in Full client but not in WebI 2) We can apply Rank in Full client but not in WebI 3) Better formatting facilities in Full client wrt WebI -Difference between Thin and Fat installations Feature BO

Create objects in your universe with date functions. Let's say your DB is Oracle. In your "Select" statement of new object called year, try to_char(INVOICE_DATE, 'YYYY') similarly for month create object called month & r epeat process, simply replace'YYYY' with 'MM' of 'MMM' in the select statement. & so on. 189. What is the difference between slice and dice and cross tab report? 

Slice and Dice: Arrangement of Data Crosstab report is for Comparison. 190. What is the difference between slice and dice and...

Cross tab report is like at the intersection of 2 dimensions measure is displayed. Like if we have two dimensions year and product and a measure revenu, revenue is displayed at the intersection of year and product. A standard report can be sliced and diced but not the crosstabed one Slice and dice is you are going to analyze the data in different angle, but drill through is like using a single value you are going to grain the data. Slice and dice means change the position of the data like move the data from rows to columns

Drill mode means allow u to analyze the data in different angles and different levels of  details. In drill mode different types of analysis's are there like drill up, drill down, drill across, drill through. Drill through means option to select any step or level directly from the current level...
