Hi Seema,

The point is that we should not remove any existing or add any extra Commit commands to the exit

The main reason i believe is as follows.....

COMMIT WORK closes all open database cursors, any attempt to continue a SELECT loop after a COMMIT WORK results in a runtime error. For the same reason, a FETCH after a COMMIT WORK on the now closed cursors also produces a runtime error. You must therefore ensure that any open cursors are no longer used after the COMMIT WORK.

Also there are Non-Catchable Exceptions

Cause: COMMIT WORK is not possible in a FORM that was called using PERFORM ... ON COMMIT

Runtime Error: COMMIT_IN_PERFORM_ON_COMMIT

Cause: COMMIT WORK is not allowed in the update.

Runtime Error: COMMIT_IN_POSTING
