LEAVE LIST-PROCESSING
Other versions: 7.31 | 7.40 | 7.54
Syntax
LEAVE LIST-PROCESSING.
Effect
This statement immediately exits the list processor. The runtime environment continues processing with the
PBO event of the dynpro from which
the list processor was called using LEAVE
TO LIST-PROCESSING or the dynpro that was set using the addition AND RETURN TO SCREEN of this statement.
If the statement is not executed when the list is displayed by the list processor, it is ignored, except in the event blocks for reporting events. Here, the processor branches to the end of the program and continues in accordance with the process flow for executable programs.
When the list processor is exited, the list buffer of the dynpro sequence is initialized. New output statements describe a new basic list.
Example
This example shows the recommended procedure for displaying lists during dynpro sequences. A separate dynpro 500 is defined for calling the list processor. The
screen of this dynpro does not contain any screen elements and calls a single PBO module call_list but no
PAI modules. The full basic list,
including the GUI status, is defined in the PBO module. When the dynpro is exited using LEAVE
SCREEN, its processing is stopped and the list processor is started. The list events are handled in the same program. When the list processor is exited, the dynpro sequence of dynpro 500 is ended, because the
next dynpro 0 is specified when the list processor is called.
