Set text field in screen visible again after user command

in my PBO Module I have something like this:

  LOOP AT SCREEN.
    IF screen-name EQ 'LBL_TEST'.
      screen-invisible = '1'.
      MODIFY SCREEN.
    ENDIF.
  ENDLOOP.

I want to set 'LBL_TEST' visible again after some User-Command in the PAI-Module. How can I do it?

Best regards, Timur

Solution

  • You have to do it in PBO. You can set a global parameter when your operation completed and then check it. Like:

    DATA: gv_checker.

PROCESS AFTER INPUT.
 case ok_code.
   when 'some_opp'.
     gv_checker = 'X'.
 endcase. 
PROCESS BEFORE OUTPUT.
LOOP AT SCREEN.
    IF screen-name EQ 'LBL_TEST'.
      screen-invisible = '1'.
      MODIFY SCREEN.
    ENDIF.
    if IF screen-name EQ 'LBL_TEST' and gv_checker = 'X'.
      screen-invisible = '0'.
      MODIFY SCREEN.

    endif.
ENDLOOP.
