Listbox item selection event should hide another Parameter - Problem

Former Member — Mon, 12 Jul 2010 11:59:05 GMT

Hello,

As everyone of you may know that we can use a listbox item selection to hide other parameter in a report.

Like for instance, if user selects an item in listbox then we will usually loop at screen and make other radio button fields visible / invisible.

I am able to hide the radio buttons but when i try to set a parameter ( textbox like ) then i can see the parameter ( textbox ) filled with stars ********

Why a radio button is hiding successfully and not a textbox parameter ?

Can someone help me how to hide a textbox parameter?

Thank you.

Hi,

first make tat text field input disable and then invisible ,

SCREEN-INPUT = 0.

SCREEN-INVISIBLE = 1.

MODIFY SCREEN.

this will work , hope this helps you

Hi Madhukar Shetty ,

Thank you so much for your reply.

Your idea helped me a lot. I would like to hide the corresponding text element along with the Parameter ( textbox ).

Can you please suggest me ?

Thanks in advance.

I would like to hide the corresponding text element along

If its a module pool , then yu can use field screen-name to do this.

Hi Keshav,

If it is a module pool then you are right. But my problem here is with the Report.

Can anyone suggest me a solution for this Text element hiding in reports?

Thanks in advance.

Hi,

Have you tried with MODIF ID ?

PARAMETERS
     : p_test        TYPE char01,
       p_nor         TYPE char10
                     MODIF ID nor.

AT SELECTION-SCREEN OUTPUT.

  LOOP AT SCREEN.
    IF screen-group1 = 'NOR'.
      screen-active = 0.
      MODIFY SCREEN.
    ENDIF.
  ENDLOOP.

Regards

Hi,

Here is my code.

PARAMETERS: P_BENEF AS LISTBOX VISIBLE LENGTH 35 USER-COMMAND abc.

PARAMETERS: 
P_RFQ_NO LIKE EKKO-EBELN MODIF ID bl2, 
P_COL_NO LIKE EKKO-SUBMI MODIF ID bl3.

INITIALIZATION.
* Populate list box values
  name = 'P_BENEF'.
  value-key = '1'. value-text = 'Value1'.
  APPEND value TO list.
  value-key = '2'. value-text = Value2'.
  APPEND value TO list.

  AT SELECTION-SCREEN OUTPUT.
* Set list box with value
  CALL FUNCTION 'VRM_SET_VALUES'
    EXPORTING
      id     = name
      values = list.

* Control the display of screen components
  LOOP AT SCREEN.
    IF P_BENEF = 1.
      IF screen-name  = 'P_RFQ_NO'.
        SCREEN-INPUT = 1.
        screen-invisible = 0.
      ELSEIF screen-name  = 'P_COL_NO'.
        SCREEN-INPUT = 0.
        screen-invisible = 1.
      ENDIF.
      MODIFY SCREEN.
    ELSEIF P_BENEF = 2.
      IF screen-name  = 'P_RFQ_NO'.
        SCREEN-INPUT = 0.
        screen-invisible = 1.
      ELSEIF screen-name  = 'P_COL_NO'.
        SCREEN-INPUT = 1.
        screen-invisible = 0.
      ENDIF.
      MODIFY SCREEN.
    ELSEIF P_BENEF = space.
*      clear: P_RFQ_NO,P_COL_NO.
    ENDIF.
  ENDLOOP.

Hi,

Instead of SCREEN-NAME you have to use SCREEN-GROUP1 as i have mentioned in my previous post. You have not changed that in you code

Something like this

LOOP AT SCREEN.
     IF screen-group1  = 'BL2'.
       SCREEN-ACTIVE = 0.
     ELSEIF screen-group1  = 'BL3'.
       SCREEN-ACTIVE = 0.
     ENDIF.
     MODIFY SCREEN.
     IF screen-group1  = 'BL2'.
       SCREEN-ACTIVE = 0.
     ELSEIF screen-group1  = 'BL3'.
       SCREEN-ACTIVE = 0.
     ENDIF.
     MODIFY SCREEN.

*      clear: P_RFQ_NO,P_COL_NO.

 ENDLOOP.

Change the code accordingly

Regards

Now i understand i should put screen items in a group and make SCREEN-ACTIVE = 0 instead of SCREEN-INSIVIBLE =1.

Thanks everyone.
