How to retrieve data from a function module and use it in sap script??

Question

I have a report program, which calls a function module. This function module internally calls an include program. In this program, I have a variable which is to be used in the sap script. How can I send this variable to the sap script

Hi,
In your case, Include prog is part of FM, no need to treat it as an Entity.
Now, Your Answer -
In SCRIPT - IN Page Window -->
     PERFORM GET_MVAT_TIN IN PROGRAM Z_SCRIPT_PERFORMS_ABAPDB3
     USING &VBDKR-KUNRE&
     CHANGING &STCD1&
     CHANGING &STCD2&
     ENDPERFORM
     IF &STCD1& <> ' '
     <B>MVAT Number :</> &STCD1&
     ENDIF
Then go to SE38 --> Creat prog with type - Subroutine pool
In that Write FORM statement for this PERFORM.
FORM get_mvat_tin TABLES inttab STRUCTURE itcsy
                         outtab STRUCTURE itcsy.
  DATA : v_kunre TYPE kna1-kunnr,
         v_stcd1 TYPE kna1-stcd1,
         v_stcd2 TYPE kna1-stcd2.
  LOOP AT outtab.
    CLEAR outtab-value.
    MODIFY outtab.
  ENDLOOP.
  READ TABLE inttab INDEX 1.
  v_kunre = inttab-value.
  IF v_kunre CA sy-abcde.
  ELSE.
    UNPACK v_kunre TO v_kunre.
  ENDIF.
   " Here You can take your Funcion module ***************************
  SELECT SINGLE stcd1 stcd2 FROM kna1 INTO (v_stcd1, v_stcd2)
                                     WHERE kunnr = v_kunre.
  IF sy-subrc = 0.
    READ TABLE outtab INDEX 1.
    WRITE v_stcd1 TO outtab-value.
    MODIFY outtab INDEX 1.
    READ TABLE outtab INDEX 2.
    WRITE v_stcd2 TO outtab-value.
    MODIFY outtab INDEX 2.
  ENDIF.
ENDFORM.
