Description

This program declares a selection screen with two parameters that both refer to the column CARRID of the database table SPFLI. While the dictionary input help is used for p_carr_1, a separate input help is programmed for p_carr_2. Dynpro 100 is called for this. In the flow logic, the dialog module value_list is called at the PBO event. The screen of dynpro 100 is not required and the system does not call any dialog modules at PAI time.

  MODULE value_list.
PROCESS AFTER INPUT.

The dialog module value_list suppresses the display of the screen layout of dynpro 100 and switches to a list display. The list contains values for the parameter p_carr_2. These values are also placed in the HIDE area. When a line is selected from the value list, the event AT LINE-SELECTION is raised, and the selected value is passed from the area HIDE to the field p_carr_2. If a valid line is selected, the system switches directly from the event block AT LINE-SELECTION back to the selection screen and fills the corresponding input field.
