ABAP_DESCRIPTION
In this example, the system branches to list processing while screen 100 is being processed. The screen layout of screen 100 has a single input field, the component CARRID of the structure SDYN_CONN from the ABAP Dictionary. The flow logic of screen 100 is as follows:
MODULE status_0100.
PROCESS AFTER INPUT.
MODULE cancel AT EXIT-COMMAND.
MODULE user_command_0100.
In the PAI module user_command_0100 , CALL SCREEN is used to call screen 500. Screen 500 encapsulates a basic list. The flow logic of this screen is as follows:
MODULE call_list_500.
PROCESS AFTER INPUT.
The module call_list_500 defines the basic list and branches to the list display. Since the system branches to the next screen 0 after returning from the list display, screen 500 represents a screen sequence with a single screen only. When list processing is completed, the system returns to after the callpoint in user_command_0100 .
Selecting a line in the basic list creates a details list. The event block for AT LINE-SELECTION has been programmed for this purpose. In addition, the page headers for the basic and details list are defined in the event blocks for TOP-OF-PAGE and TOP-OF-PAGE DURING LINE-SELECTION .
Since only one list system is used in this program, separate control during list event processing is not necessary.
