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

former_member196331 — Wed, 05 Aug 2015 08:43:18 GMT

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.

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.

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.

if sy=subrc = 0.

Hi,

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

AT SELECTION SCREEN.

CLEAR : P_VBELP.

Thanks.

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

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 ,

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.

Regards
