ABENABAP_MESSAGE_UPDATE - ABAP MESSAGE UPDATE

- Updates

During updates, the behavior of messages depends on the work process.

• During synchronous updates and asynchronous updates in an update work process in an update session, all messages except type S cause the update to terminate without creating a runtime error. The update work process performs a database rollback, enters appropriate comments in the associated database tables VB..., and notifies the user whose program created the entries by SAPmail.

• During local updates, all messages apart from type S and X are converted to messages of type A and these behave in the same way as in dialog processing, which means they lead to a termination and a database rollback. Messages of type S and X are also handled in the same way as in dialog processing.

Notes

• In exceptional cases, an update work process may be connected to a dialog (for example, during debugging). Messages then behave as in local updates.

• In updates, type A messages cannot be caught using the predefined exception error_message in function module calls, since here the statement ROLLBACK WORK is executed implicitly, and this is not allowed in updates. Therefore, the runtime error MESSAGE_ROLLBACK_IN_POSTING is produced when type A messages are caught using error_message. Messages of types I, W, and E, on the other hand, can be caught.
