    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. <b>BAPIRET2 </b>or <b>BAPIRETTAB</b>) in order to return messages to the caller of the BAPI.

    Why is such a RETURN parameter <i>mandatory</i>?

    BAPIs are usually used for <b>external </b>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 <b>collect </b>all messages (in the RETURN parameter) and stop processing as soon as they encounter any AEX message (Abort, Error, Dump).
