Behavior of messages

When you send a message using statement MESSAGE, it must be classified with a one-character message type. The message type defines how the message is displayed and determines the subsequent program flow. Valid message types are "A", "E", "I", "S", "W", and "X". These stand for termination message, error message, information message, status message, warning, and exit message.

The system behavior after a message of a particular type is sent is context-dependent:

• Messages in dialog processing

• Messages in controlprocessing

• Messages in batch input

• Messages in background processing

• Messages in updating

• Messages in conversion routines

• Messages in procedures

Notes

• Messages are mainly intended for use during dialog processing, and there for the event PAI. Here, messages of type "E" and "W" permit an error dialog. to be used in connection with the statement FIELD of the dynpro structure logic. Therefore, messages of type "E" or "W", in particular, should never be used in other contexts.

• As of release 6.20, you can use assertions as an alternative to generating runtime errors with messages of type "X".
