Syncronizing (enable/disable )the subscreen with main screen

Former Member — Fri, 27 Feb 2009 15:47:09 GMT

Hi Experts,

I have implemented a screen exit (MM06E005)in me22/23 for customer data.This comes as a tab in PO header. Now the issue that i am facing is when i click change/display button i need to enable and disable the fields of my subscreen just like the main screen (both should get enabled and disabled together) but the issue is that change/display button will have always the same sy-ucomm so wether it needs to be enabled or disable is hard to figure out.

what i have done is that i have taken a flag which changes to 'C' to 'D' whenever user clicks the change/display button. for most of the time it works fine but many times when user clicks other buttons like save /change object this logic fails and i need to handle sy-ucomm of all these buttons.........what i feel is that this is not a clean logic and surely there would be a better way to syncronize the main screen and subsceen so they both are enabled and disabled at same time .

below is my code.

declaration in topinclude
     gv_disp(1) value 'D', "for me23n
      gv_disp1(1) value 'C'. "for me22n.

code in pbo

IF sy-tcode = 'ME23N'.
    IF gv_ucomm EQ ''. " when the transaction is called for the first time
      LOOP AT SCREEN.
        screen-input = 0.
        MODIFY SCREEN.
      ENDLOOP.
    ELSEIF gv_ucomm EQ 'MESAVE'. " When save button is clicked
      LOOP AT SCREEN.
        screen-input = 0.
        MODIFY SCREEN.
      ENDLOOP.
      gv_disp = 'D'.
    ELSEIF gv_ucomm EQ 'MECHOB'. " When save change object  is clicked
      LOOP AT SCREEN.
        screen-input = 0.
        MODIFY SCREEN.
      ENDLOOP.
      gv_disp = 'D'.
    ELSEIF gv_ucomm EQ 'METOGG'. " change/display button is clicked then we need to flipflop the screen.
      IF gv_disp = 'D'. "Display mode
        gv_disp = 'C'.   "change mode
        LOOP AT SCREEN.
          screen-input = 1.
          MODIFY SCREEN.
        ENDLOOP.
      ELSE.
        LOOP AT SCREEN.
          screen-input = 0.
          MODIFY SCREEN.
        ENDLOOP.
        gv_disp = 'D'.
      ENDIF.
    ENDIF.
  ELSEIF sy-tcode = 'ME22N'.
    IF gv_ucomm EQ ''.
      LOOP AT SCREEN.
        screen-input = 1.
        MODIFY SCREEN.
      ENDLOOP.
    ELSEIF gv_ucomm EQ 'MESAVE'.
      LOOP AT SCREEN.
        screen-input = 0.
        MODIFY SCREEN.
      ENDLOOP.
      gv_disp1 = 'D'.
    ELSEIF gv_ucomm EQ 'MECHOB'. " When save change object  is clicked
      LOOP AT SCREEN.
        screen-input = 1.
        MODIFY SCREEN.
      ENDLOOP.
      gv_disp = 'C'.
    ELSEIF gv_ucomm EQ 'METOGG'.
      IF gv_disp1 = 'D'. "Display mode
        gv_disp1 = 'C'.   "change mode
        LOOP AT SCREEN.
          screen-input = 1.
          MODIFY SCREEN.
        ENDLOOP.
      ELSE.
        LOOP AT SCREEN.
          screen-input = 0.
          MODIFY SCREEN.
        ENDLOOP.
        gv_disp1 = 'D'.
      ENDIF.
    ENDIF.
  ENDIF.

I did not go thru ur entire code but I have a strong feeling that you need to add some conditions like you should not be allowing the user to save or change in display mode
