Field Validation for Authorization Object field on selection screen

Question

Hi Experts,
We have included a new field u2018Authorization Objectu2019 in the selection screen which should be reflected in the field Authorization Object of the spool property. Please let us know how we can provide F4 help for this field and also validate it in the code.
The data element "RSPOAUTH" is used for the field on selection screen parameter. However, as there is no value table attached to the domain, we are unable to provide any F4 help and hence cannot validate the field in the code.
Looking forward for your valuable reply.
Thanks in advance.

   You can refer the following code for getting F4 help.

         zesgbtc TYPE zhr_del_btc,
       END OF stru_btc.
DATA: it_btc TYPE STANDARD TABLE OF stru_btc
SELECT-OPTIONS: s_zzbtc FOR pa0001-zzbtc NO INTERVALS.
AT SELECTION-SCREEN ON VALUE-REQUEST FOR s_zzbtc-low.
  SELECT * FROM zbtc INTO CORRESPONDING FIELDS OF TABLE it_btc.
  CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'
    EXPORTING
      retfield        = 'BTC'
      dynpprog        = sy-repid
      dynpnr          = sy-dynnr
      dynprofield     = 'S_ZZBTC'
      value_org       = 'S'
    TABLES
      value_tab       = it_btc
    EXCEPTIONS
      parameter_error = 1
      no_values_found = 2
      OTHERS          = 3.
  IF sy-subrc <> 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
        WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
  ENDIF.
Hope this will help you.
