Re: Grey out screen Fields after entering input using F4 help without an enter code

Hello Kunal,

Try below code, it works for me.

TABLES : MARA.

DATA: BEGINOF IT_MARA OCCURS 0,

MATNR LIKE MARA-MATNR,

ENDOF IT_MARA.

DATA : IT_RETURN TYPESTANDARDTABLEOF DDSHRETVAL WITHHEADERLINE.

 

PARAMETERS: p_matnr LIKE mara-matnr.

 

ATSELECTION-SCREENONVALUE-REQUESTFOR p_matnr.

  SELECT MATNR FROM MARA UPTO10ROWSINTOTABLE IT_MARA.

  SORT IT_MARA BY MATNR.

  DELETEADJACENTDUPLICATESFROM IT_MARA COMPARING MATNR.

 

CALLFUNCTION'F4IF_INT_TABLE_VALUE_REQUEST'

    EXPORTING

      RETFIELD      = 'MATNR'

      DYNPPROG      = SY-REPID

      DYNPNR        = '1000'

      DYNPROFIELD    = 'P_MATNR'

      VALUE_ORG      = 'S'

    TABLES

      VALUE_TAB      = IT_MARA

      RETURN_TAB    = IT_RETURN

    EXCEPTIONS

      PARAMETER_ERROR = 1

      NO_VALUES_FOUND = 2

      OTHERS        = 3.

 

  IF SY-SUBRC <>0.

    MESSAGEID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO

            WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.

  ENDIF.

  LOOPATSCREEN.

    IF SCREEN-NAME EQ'P_MATNR'.

    SCREEN-INPUT = '0'.

    MODIFYSCREEN.

    ENDIF.

  ENDLOOP.
