How could i Clear the parameter value once select the first parameter value using f4

[former_member196331]

Hi,

I need Small information.

I have two Parameters, In My Selection Screen. Both are i need to select value  from the  Method F4IF_INT_TABLE_VALUE_REQUEST

Values are coming and  Everything is fine. Small logic it is having. I am selecting the first parameter . then i come to second parameter.

I need to pass the value parameter of first selection parameter to the second parameter sql query.

Here what i need is  After select the first parameter value , I would like to clear the second parameter value (Previously what i selected from f4)

''The below code is for first parameter, Second parameter is also same thing like this.

   Below bold color code i used for clear the values for  second parameter, If i put the break points  values are clearing.

   but it is not reflect to the front end means at selection Screen.

   Can any body tell me how could i clear the values to the Selection Screen.

I used even selection-screen output also but it is not triggering ,After select the first parameter.

selection screen output is triggering at the time of starting the code.

AT SELECTION-SCREEN OUTPUT.

   LOOP AT SCREEN.

     CASE P_VBELN.

      CLEAR: P_VBELP.

         ENDCASE.

          ENDLOOP.

Above code not working. Triggers at the time of starting Only.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR P_VBELN.

   REFRESH:  IT_ERNAM.

   SELECT DISTINCT VBELN FROM EKKN INTO TABLE IT_ERNAM.

   CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

     EXPORTING

       RETFIELD        = 'P_vbeln'

       VALUE_ORG       = 'S'

     TABLES

       VALUE_TAB       = IT_ERNAM

       RETURN_TAB      = IT_RETURN1

     EXCEPTIONS

       PARAMETER_ERROR = 1

       NO_VALUES_FOUND = 2

       OTHERS          = 3.

   P_VBELN = IT_RETURN1-FIELDVAL.

  CLEAR: P_VBELP.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR P_VBELP.

   REFRESH:IT_MATNR.

   SELECT DISTINCT VBELP FROM EKKN INTO TABLE IT_MATNR WHERE VBELN =  P_VBELN.

   CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

     EXPORTING

       RETFIELD        = 'P_VBELP'

       VALUE_ORG       = 'S'

     TABLES

       VALUE_TAB       = IT_MATNR

       RETURN_TAB      = IT_RETURN2

     EXCEPTIONS

       PARAMETER_ERROR = 1

       NO_VALUES_FOUND = 2

       OTHERS          = 3.

   P_VBELP = IT_RETURN2-FIELDVAL.

hi,

please try it.

PARAMETER : p_vbelp TYPE per_amt  MODIF ID gp1.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR P_VBELN.

   REFRESH:  IT_ERNAM.

   SELECT DISTINCT VBELN FROM EKKN INTO TABLE IT_ERNAM.

     EXCEPTIONS

       PARAMETER_ERROR = 1

       NO_VALUES_FOUND = 2

       OTHERS          = 3.

   P_VBELN = IT_RETURN1-FIELDVAL.

if sy=subrc = 0.

LOOP AT SCREEN.

          IF screen-group1 = 'GP1'.

         CLEAR val.

       ENDIF.

        MODIFY SCREEN.

   ENDLOOP.

endif.

Hi,

You need to clear the variable P_VBELP at event 'AT SELECTION SCREEN'.

AT SELECTION SCREEN.

CLEAR : P_VBELP.

Thanks.

HI,

Thanks for your reply.

I put the code before the value request but it is not firing...

May i know how could i use it.

I seen below thread. They used before the value requested i used the same way but not firing.

At selection-screen.

   CLEAR : P_VBELP.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR P_VBELN.

   REFRESH:  IT_ERNAM.

   SELECT DISTINCT VBELN FROM EKKN INTO TABLE IT_ERNAM.

   CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

     EXPORTING

       RETFIELD        = 'P_vbeln'

       VALUE_ORG       = 'S'

     TABLES

       VALUE_TAB       = IT_ERNAM

       RETURN_TAB      = IT_RETURN1

     EXCEPTIONS

       PARAMETER_ERROR = 1

       NO_VALUES_FOUND = 2

       OTHERS          = 3.

   P_VBELN = IT_RETURN1-FIELDVAL.

*  CLEAR: P_VBELP.

   IF SY-SUBRC = 0.

     LOOP AT SCREEN.

       IF SCREEN-GROUP1 = 'GP1'.

         CLEAR P_VBELP.

       ENDIF.

       MODIFY SCREEN.

     ENDLOOP.

   ENDIF.

     CALL FUNCTION 'CONVERSION_EXIT_ALPHA_INPUT'

       EXPORTING

         INPUT  = P_VBELN

       IMPORTING

         OUTPUT = P_VBELN.

It's firing. Before  coming the output .

But i need Once select the first parameter then i need to make it empty.

[Former Member]

Hi,

just add the if condition to check the variable is empty or not.

AT SELECTION-SCREEN.

IF P_VBELN IS NOT INITIAL  AND P_VBELP IS NOT INITIAL.

CLEAR : P_VBELP.

ENDIF.

Thanks.

Hi,

Thanks for your reply.

First it is not firing. Before coming the output only it is coming.

I need Once select the first parameter then only i need to validate.

[dibyajeeban_jena]

Hi ,

Here is the solution..Use FM 'DYNP_VALUES_UPDATE' , 

Please the below code in place of  'Clear : p_vbelp' (in bold above) in your code .

DATA : it_dyn TYPE TABLE OF dynpread ,
             WA_DYN TYPE DYNPREAD.

WA_DYN-FIELDNAME = 'P_VBELN' .

WA_DYN-FIELDVALUE = it_return1-FIELDVAL.

APPEND WA_DYN TO IT_DYN.



WA_DYN-FIELDNAME = 'P_VBELP' .

WA_DYN-FIELDVALUE = '   '.

APPEND WA_DYN TO IT_DYN.



  CALL FUNCTION 'DYNP_VALUES_UPDATE'

    EXPORTING

      dyname     = sy-repid

      dynumb     = sy-dynnr

    TABLES

      dynpfields = it_dyn.

  IF sy-subrc <> 0.

* Implement suitable error handling here

  ENDIF.
