Hello Lalitha

I can address one of your questions.

Since you are creating a BAPI which is a special kind of RFC-enabled function module the BAPI must have a RETURN parameter (either a structure or a table type, e.g. BAPIRET2 or BAPIRETTAB) in order to return messages to the caller of the BAPI.

Why is such a RETURN parameter mandatory?

BAPIs are usually used for external access, thus they are called via RFC. If the BAPI would throw any exceptions this would cause the RFC connection to break down. As a consequence the caller has no idea what has happened.

Instead, BAPIs collect all messages (in the RETURN parameter) and stop processing as soon as they encounter any AEX message (Abort, Error, Dump).
