Hi Prasad,

ALE Architecture:

It consists of an Outbound process, an Inbound process, and an Exception u2013 Handling process.

Outbound Process:

ALE Outbound Process in SAP sends data to one or more SAP Systems. It involves four steps.

1. Identify the need of IDoc: This step starts upon creating a application document, can relate to a change to a master data object.

2. Generate the Master IDoc: The document or master data to be sent is read from the database and formatted into an IDoc format. This IDoc is called as a Master IDoc.

3. Generate the Communication IDoc: The ALE Service layer generates a separate IDoc from the Master IDoc for each recipient who is interested in the data. Separate IDocs are generated because each recipient might demand a different version or a subset of the Master IDoc. These recipient-specific IDocs are called Communication IDocs and are stored in the database.

4. Deliver the Communication IDoc: The IDoc is delivered to the recipients using an asynchronous communication method. This allows the sending system to continue its processing without having to wait for the destination system to receiver or process the IDoc.

Inbound Process:

The inbound process receives an IDoc and creates a document in the system.

1. Store the IDoc in the database: The IDoc is received from the sending system and stored in the database. Then the IDoc goes through a basic integrity check and syntax check.

2. Invoke the Posting Module: The control information in the IDoc and configuration tables are read to determine the posting program. The IDoc is then transferred to its posting program.

3. Create the Document: The posting program reads the IDoc data and then creates a document in the system. The results are logged in the IDoc.

Hope this is clear.

Regards..
