Other versions: 7.31 | 7.40 | 7.54
REPORT demo_selection_screen_f1. PARAMETERS: p_carr_1 TYPE s_carr_id, p_carr_2 TYPE spfli-carrid. AT SELECTION-SCREEN ON HELP-REQUEST FOR p_carr_2. CALL SCREEN 100 STARTING AT 10 5 ENDING AT 60 10.
In this program, a selection screen with two parameters that are based on the data element S_CARR_ID
of the ABAP Dictionary are declared. Whereas the Dictionary documentation is used as online help for
p_carr_1, the system calls a separate screen with the number 100 for
p_carr_2. Using the Screen Painter, this screen is defined as a modal dialog box with next screen
0, which displays the required help text as text fields. You are not required to program the flow logic for this screen.
