Description

This example switches to list processing while processing dynpro 100. The screen layout of dynpro 100 has a single input field, the component CARRID of the structure SDYN_CONN from the ABAP Dictionary. The flow logic of dynpro 100 is:

PROCESS BEFORE OUTPUT.
  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 dynpro 500. Dynpro 500 encapsulates a basic list. It has the following flow logic:

PROCESS BEFORE OUTPUT.
  MODULE call_list_500.
PROCESS AFTER INPUT.

The module call_list_500 defines the basic list and branches to the list display. After returning from the list display, the system branches to the next dynpro 0, which means that dynpro 500 represents a dynpro sequence with only one dynpro. When list processing is complete, the system returns to a point after the call point in user_command_0100.

If the user selects a line on the basic list, a details list appears. This is done using the event block AT LINE-SELECTION. The program also contains event blocks for TOP-OF-PAGE and TOP-OF-PAGE DURING LINE-SELECTION, which define page headers for both the basic list and details list.

Since there is only one list system in this program, there is no need for case distinctions within the list events.
