Use the BDC_CLOSE_GROUP function module to close a session after you have inserted all of your batch input data into it. Once a session is closed, it can be processed.

BDC_CLOSE_GROUP needs no parameters. It automatically closes the session that is currently open in your program.

You must close a session before you can open another session from the same program.

You cannot re-open a session once it has been closed. A new call to BDC_OPEN_GROUP with the same session name creates a new session with the same name.
