1. Introduction to ALE We Never Compromise In Quality. Would You? ALE (Application Linking and Enabling)

ALE is SAP'S technology to support distributed yet integrated processes across several SAP systems. (OR) Application Link Enabling (ALE) is a set of business processes and tools that allow applications on different computer systems to be linked. This can be done between different SAP systems as well as between SAP and non-SAP systems. Distributed Process:

A distributed process is one in which part of a business process(Sa1es) is carried out on one system and part(Finance) on another. The two systems each other at appropriate points to stay synchsonized. Need for Distributed Process:

Business in D No11 availability of dedicated net Cultural and 1 Maintenance downtime etc.).

. It was inlpoi-tan: from data on businlss rules, not on database ng integrated as one endently and support Distributed systems that can handle different data models. A local implementation should be able to customize the system to meet its local needs. Receiving systems that can handle their own problems and not tie up the sending system. Systems that maintain continued operation in spite of network failure. Changes made to either system should be syncl~ronizedafter the network connection is restored. A sound technology and methodology that can be used in all distribution scenarios. SAP Distributed environment: ALE allows for efficient and reliable communication between distributed processes across physically separate SAP systems. ALE is based on application to application integration using messaging architecture. A message defines data that is exchanged between two processes. IDocs are containers that hold data exchanged between the two systems.

Benefits of ALE -

Integration with non-SAP systems: ALE architecture allows third party applications to integrate with SAP system. Reliable Distribution: Once message type created and the receiver of the message is determined, ALE delivers the message to the recipient. If there is any network problem it will buffer the message and delivers the message once the network is restored. It also ensures that the message is not delivered twice. Release Upgrade: Any of the distributed system can be upgraded to the new release of SAP without affecting the functionality. backward compatibility of messages ALE may also reduce costs, in particular costs of is run on one integrated system you have to upgrade the who1 entire company is affected for the new release. Within interfaces, like those provi not involved and need no tra

known to all ass all associates as soon

you to immediately trigger an IDoc sent to er record is created in one system.

Another common scenario is that a company uses different installations for company accounting and production and sales. In that case, ALE allows you to copy the invoices created in SD immediately to the accounting installation.

2. IDocs & Message Type in Detail We Never Compromise In Quality. Would You?

IDocs Note : ALE Uses IDoc(1ntermediate Document) to carry the Data across the Distributed Systems. Note : IDoc is SAP'S Own Foimat so that only SAP Systems Can Understand the data in IDoc Format. Scenariol:

SAP - SAP

Note : Since Both the systems are SAP Systems, they ca IDoc Format. Scenario2: SAY Non -SAP /*

EAI(Enterprise Application Jiitegration) Tools

When the Communication is bet SAP Non SAP , The data in IDoc Format should be Converted in other f o r r & t ( ~here) ~ ~ and the Any other format should be converted into IDoc , We Can go for any EAI Tool which can do the above Conversion With no Loss Of Data. Note : IDoc is Collection of Segments AND Each segment is collection Of Fields. Note :SAP ALE Consultant role is always to Work with IDocs irrespective of the Other System(SAP/Non-SAP).

2. IDocs & Message Type in Detail We Never Compromise In Quality. Would You? /DOC Design Guide Lines(Syntax Rules)

IDOC Type defines the structure and format of the business document that is to be exchanged. Analyze the Application Data to be transferred Via IDoc AND Identify the List Of required Segments Make Sure that the related data is grouped into one segment Decide the Parent & Child Segments Decide the Minimum & Maximum No Of Repetitions of each Segment Decide the mandatoryloptional segments Make Sure that the Segment length is not more than 1000 bytes(Char). Segments

Reduced IDoc Type This Technique allows to the field level i.e we can specify the list Segments and Segment Fields allowed to the receivers. Scenario : Two Systems A and B ,decided to Maintain the Standard Price for Material master Data Locally on their Systems. They want to receive very limited data from the Central System. So that We Can Reduce the Standard IDoc to the Reduced IDoc with the Required list Of Segments and Segment Fields. Note : The Reduced IDoc type gets a New Message type and the the Reduced IDoc type is defined from the Standard IDoc by Enabling and Disabling the List Of Segments and Even fields . Note : In Both Distribution Model and Outbound Partner Message type should be Configured.
