What does this 'USER-COMMAND run' do?

AT SELECTION-SCREEN OUTPUT.

  IF p_app = 'X'.
    LOOP AT SCREEN.
      CHECK SCREEN-NAME = 'P_LFILE'.
      SCREEN-ACTIVE = 0.
      MODIFY SCREEN.
    ENDLOOP.
  ELSEIF p_pre = 'X'.
    LOOP AT SCREEN.
      CHECK SCREEN-NAME = 'P_AFILE'.
      SCREEN-ACTIVE = 0.
      MODIFY SCREEN.
    ENDLOOP.
  ENDIF.

When you add the option USER-COMMAND to the first radiobutton in a group, it will trigger the AT SELECTION-SCREEN OUTPUT everytime you click a radiobutton in that group.

Here is the current codes. How come the PERFORM 1100_modify_sel_screen

does not work? both fields are open.

So the 'USER-COMMAND' associates with AT SELECTION-SCREEN OUTPUT. How about the 'run'? why need a name 'run' without any association?

Thanks,

Helen

The parameter names have to be in UPPERCASE.

Thank you. I got the good result. Would you please explain why need the 'run' after the 'USER-COMMAND'?

Thanks,

'RUN' is the user-command that you assigned to your radiobutton group activity. It can be any name XYZ. When you click on any radiobutton in that group, the field sy-ucomm will be filled with the value 'RUN'. Knowing this value will be helpful if you are dealing with many dynamic changes on the screen depending on the user actions. But if you are using it the way you are currently using, then the only help it is doing is triggering the AT SELECTION-SCREEN OUTPUT everytime you move from one radiobutton to another in that group.
