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.
This program declares a selection screen with two parameters both referring to the data element
S_CARR_ID from ABAP Dictionary. While the dictionary documentation is used as online help for
p_carr_1, a separate dynpro with the number 100 is called for
Using Screen Painter, this dynpro is defined as a modal dialog box with the next dynpro 0, which displays the required help text as text fields. The screen does not require any flow logic.
