Multiple Selection-Screen Issue

[Former Member]

Hello everyone,

I am creating a program that is prompting the user to either enter inputs, or reference a file that has inputs. When I use the below code, the program creates a begin screen that prompts the user, then correctly navigates to the manual / file input reference. The issue comes when the user inputs the information then clicks execute, the program does not process, but when you click (F3) back, the program processes.

perform UPDATE_OPEN_CHECKS.
else.
call SELECTION-SCREEN 200.
perform READ_UNIX_FILE.
endif.

Be careful, AT SELECTION-SCREEN is called after input for any of the 3 selection screens (1000, 0100, 0200). You should test the system variable SY-DYNNR (screen number) to decide which code to run.

Thank you, Sandra. I updated to the code below and it looks to work properly now.

You don't need anymore SY-DYNNR because your code is in event START-OF-SELECTION (SY-DYNNR is to be used only in events AT SELECTION-SCREEN).

Moreover, the event END-OF-SELECTION is not needed as it doesn't contain any code (and it's usually only for the obsolete "logical databases").

Or, hide the fields dependant on the value of the radio buttons. Then on the at selection screen output event, either activate or deactivate the fields. that is a lot simpler than having to handle sub screens and the like. You then end up with a standard report and making decisions based upon parameters rather than screen numbers.
