Introduction As the time goes on any database system can suffer from performance issues due to large volume of data. Once data volume is high, it uses more resources hence system performance get dropped. To avoid such cases, data which is no longer used by the system should be removed from the database and kept in a separate place for later references. During archiving, data is automatically compressed by up to a factor of 5. This process is known as Archiving.

Advantages of database archiving 

Resolves storage space and performance problems caused by large volumes of transaction data



Makes master data easier to handle and to keep up to date



Ensures statutory data retention rules are observed



Ensures that data can be re-used at a later date, for example in new product development.

What is an Archiving Object? The archiving object is the core of the SAP archiving concept. The archiving object determines what is archived and how. It also describes which database objects must be handled together as a commercial object and which must be interpreted independently. Data in the R/3 Database can only be archived using archiving objects, which describe the data structure and context.

Archive Information System The Archive Information System (AS) is a generic tool for indexing data archives and is fully integrated into the SAP Data Archiving environment. The indexes created with this tool, which are called Archive Information Structures, are used to display archived data. First you should check if an information structure already exists that you could use for reporting. You can then change this information structure to suit your needs. If there is no information structure available that you can use, you can create a new one. You define the information structure to be used for archive reporting. In doing this, you specify which source fields from the archive are copied to which fields in the information structure. You do this with the help of application-specific field catalogs, which are included in the features of the Archive Information System.

In simple terms, if you need to retrieve data after archiving took place, you need to activate all relevant info structures for that archive object first.

How to find the relevant Info Structure for each object Transaction: SARA 

Press button option Same can be directly reached through the transaction SARI.

 

Click on button User search help or Press “F4” under “Archiving Info structure” field



Use search option in the F4 help



Enter relevant archive object under

field and press Enter key



You’ll be able to see all relevant “Info structure” for that object here.

Important: You have to find relevant info structures for all your archiving objects before archiving any data. Then you need to activate those.

How to activate info structures Transaction: SARA 

Press button option Same can be directly reached through the transaction SARI.

 

Press on button. Transaction: SARJ will get you to the same window as well. Enter relevant info structure

 

Press button If it’s successful, system will give a message like this;

Important: Same has to be done for all relevant info structures in all relevant archive objects. For example, for archiving object: SD_VBAK; you have to activate below info structures.

How to fill an Info Structure This step is optional. (Only if you have done archiving without activating Info structures) During an archiving delete run all (activated) archive information structures belonging to an archiving object are filled automatically. Also the Archive Development Kit (ADK) transfers all data records found in the archive to the AS interface. From the defined info structure, the AS filters the data from the data records transferred and enters it in a transparent database table together with an access key. This table serves as the basis for later searches. This function allows you to fill an information structure with data from the available archives if the delete program has already processed those archives. Transaction: SARA



Click on

button

You can directly access this window from the transaction SARI



Click on



Enter “Archive Object” and press



You can view the status of all relevant info structures here from the traffic light system.

How to create a new info structure This step is optional. If required; you can create new info structures to read archived data. An information structure is only valid for one archiving object. Several information structures can be defined for one archiving object. Eg: For archiving object SD_VBAK; you have below set of info structures.

Transaction: SARA 

from “Optional fields” table to “Info structure fields” table by highlighting and clicking button



Once done, Press

Now you have created a new info structure. You need to activate this structure before using it for archiving. To activate it; please refer; “How to activate info structures” section in this document.

Archiving Configuration steps Transaction: SARA This transaction is a one stop shop for all archiving related settings, such as customizing, pre-processing, archiving, deleting, reading, management, etc. Before archiving an object, you need to customize relevant settings. 

Enter relevant Archive object



Press

button

Cross – Archiving Object Customizing 

Accept all default settings in

section

You can review the defaults and update them appropriately. For example, you may want the system to check for files in the file system or for stored files, have the system verify the archive file existence before deleting, indicate the maximum amount of data you can write to the archive file, and give the name of the server group name for a background job.

Archiving Object – Specific Customizing 

Click on section

This has to be done to all relevant objects. Define Delete jobs Once archiving is done, you need to delete archived data from the data base. You can setup this in 3 ways. This you can define under “Delete Jobs” section.

Select



if you want to manually carry out deleting.

Once done, Press

Basis Customizing In this step you have to define the archive file path. This path is a global setting for the entire client. (Object Independent) You can specify the external storage system and based on the configuration, the system automatically transfers the archived files to the subsystem. You should link the external storage system to the SAP system for file transfer. If you haven't specified the external storage system, you can use the SAP Content Management Infrastructure. As the name specified, this is done by basis consultants. 

Click on

Here you specify cross- client file paths.

Highlight the relevant System details and click on

option.



As per my example, my archive files are saved to “G:\usr\sap\archive\”

Application Specific Customizing Define “Residence time” for Archiving object What is Residence time? The residence time refers to the amount of time that has to pass before a business object to be archived. Residence time is measured in number of days and is entered in application-specific Customizing for a specific archiving object. The residence time can begins either with the creation date of the document, or with the last change date. Transaction: SARA 

Press



Click Section

button under “Application-Specific Customizing”

Now you need to maintain Spool Parameters for the archiving process. What are Spool Parameters and why? Controls the print output of the generated archiving log. You can choose Properties to maintain additional properties of the spool request. You do not generally change these properties for each spool request. If you have not configured any printer Enter LP01 or LOCL .These output types comes with the system and just create spool and the spool will be deleted based on the Basis Configuration. Spool parameters that are already specified in the user defaults or in the user-specific print parameters are automatically applied. Otherwise, you only have to specify the spool parameters for the execution of the first ction in an archiving session. They are retained until the end of the archiving session.
