Authorization check for selection option

I want to share AUTHORITY-CHECK OBJECT for selection opting.

SELECTION-SCREEN BEGIN OF BLOCK b1 WITH FRAME TITLE text-002.
PARAMETERS:p_bukrs type bkpf-bukrs OBLIGATORY.
SELECT-OPTIONS :  so_audat FOR vbak-audat OBLIGATORY,
      so_auart FOR vbak-auart OBLIGATORY,
      so_kunnr FOR vbak-kunnr,
      so_matnr FOR vbap-matnr,
      so_vrkme FOR vbap-vrkme OBLIGATORY,
      so_lgort FOR vbap-lgort,
      so_werks FOR vbap-werks,
      so_vkorg FOR vbak-vkorg,
      so_vtweg FOR vbak-vtweg,
      so_spart FOR vbak-spart.
SELECTION-SCREEN END OF BLOCK b1.

Want to check Authorization for so_vkorg, so_vtweg, so_spart.

Go to AT SELECTION-SCREEN OUTPUT.
Now AT SELECTION-SCREEN.
Call  V_VBAK_VKO.

Check the code.

SELECT *
FROM  vbak
          INTO TABLE tmp_vbak
         WHERE audat IN so_audat
      AND auart IN so_auart
      AND vkorg IN so_vkorg
      AND vtweg IN so_vtweg
      AND spart IN so_spart
      AND bukrs_vf = p_bukrs.

   LOOP AT tmp_vbak INTO  wa_tmp_vbak.
     AUTHORITY-CHECK OBJECT 'V_VBAK_VKO'
        ID 'VKORG' FIELD  wa_tmp_vbak-vkorg
        ID 'VTWEG' FIELD  wa_tmp_vbak-vtweg
        ID 'SPART' FIELD  wa_tmp_vbak-spart
        ID 'ACTVT' FIELD '03'.
   ENDLOOP.
   IF sy-subrc <> 0.
     MESSAGE 'No authorization' TYPE 'E'.
   ENDIF.

Hope it will work
