How to enable a field in selection screen based on the value, selected from a drop down list?

[former_member308418]

Dear All,

In my selection screen, by default a field is made disable. I want to make this field enable if user chooses a specific condition from a drop down list. Please suggest how to do that.

Thanks.

With regards.

Just manage it in the PBO (AT SELECTION-SCREEN OUTPUT) trigger this event by assigning some dummy function code to the drop-down list.

Dear Raymond,

Thanks a lot. I am using this event to make my fields enable or disable. This event not captures the selected condition.

For example,

AT SELECTION-SCREEN OUTPUT.

   LOOP AT SCREEN.

     IF p1 = 'X'.

       IF r1 = 'X'.

         IF screen-group1 = 'M1'.

           screen-input = 0.

         ENDIF.

         IF screen-group1 = 'M2'."

           screen-input = 0.

         ENDIF.

...............................

............................

ENDLOOP.

I want this group M2 to be enabled after user selects a specific condition from the drop down list.

Hello,

It is not working because you are not using MODIFY SCREEN before ENDLOOP.

Bests.

I have not posted the whole code here. Actually Modify Screen is there in my coding. I use breakpoint here and saw this event not captures the selected condition value.

Dd you miss my

trigger this event by assigning some dummy function code to the drop-down list.

Try a code like

PARAMETERS: p_field1 TYPE text20 AS LISTBOX VISIBLE LENGTH 50 USER-COMMAND dummy, " trigger PAI/PBO cycle
            p_field2 TYPE text20 MODIF ID m2.

AT SELECTION-SCREEN OUTPUT.
  LOOP AT SCREEN.
    CASE screen-group1.
      WHEN 'M2'.
        IF p_field1 EQ 'SOMEVALUE'. " internal format!

          screen-input = '1'.
        ELSE.
          screen-input = '0'.
        ENDIF.
    ENDCASE.
    MODIFY SCREEN.
  ENDLOOP.

Hello,

You can adjust below code according to your requirement.

Regards.

SELECTION-SCREEN BEGIN OF BLOCK a1 WITH FRAME TITLE text-000.

SELECT-OPTIONS : s_default FOR vbak-erdat  MODIF ID S2.

PARAMETERS : p_dropdwn type spmon MODIF ID S1.

SELECTION-SCREEN END OF BLOCK a1.

AT SELECTION-SCREEN OUTPUT.

    LOOP AT SCREEN.

      IF p_dropdwn = 'X' AND screen-group1 = 'S2'.
        screen-active = '0'.
      ENDIF.

      MODIFY SCREEN.
    ENDLOOP.

Dear Ekrem,

Thanks a lot. AT SELECTION-SCREEN OUTPUT not catches the value of selection screen fields. Though I tried with this logic and failed.

Hi Mr. anonymous,

use PARAMETER addition USER-COMMAND fcode for the listbox parameter. This triggers PAI and then PBO. In PBO you can use the LOOP AT SCREEN as suggested.
