SAPscript external subroutine - select not pulling data

Question

Hi all,
I am calling an external subroutine in my SAPscript. In this subroutine, I am using a simple select statement:
* get sales order number
  SELECT vbelv posnv
    FROM vbfa
    INTO CORRESPONDING FIELDS OF TABLE it_so
     WHERE vbeln = gv_deldoc
       AND posnn = gv_posnr.
The problem is no data is being pulled into it_so. I have confirmed in VBFA (through SE16N) that data exists in the system so this isn't the problem. Are there restrictions with using selects in SAPscript?
Thanks,

Answer 1

Hi,
Please refer below code.
In SAP Script ,SE71: call the subroutine pool program with the below sysntax.
/: PERFORM GET_DATA IN PROGRAM ZXXXX
/: USING &XXXX-MATNR&
/: CHANGING &V_YYYY&
/: CHANGING &V_YYY2&
/: ENDPERFORM
Using Parameter will be the input in the subroutine pool to fetch the data.
Changing Paramter will be the your output to pass the data into SAP Form.
now goto SE38,and create a subroutine pool program with the name ZXXXX,follow the below code.
FORM get_data TABLES tbl_in  STRUCTURE itcsy
                       tbl_out STRUCTURE itcsy.
READ TABLE tbl_in INDEX 1.
  IF sy-subrc EQ 0.
    XXXX-Matnr = tbl_in-value.
"Pass it through the conversion exit CONVERSION_EXIT_ALPHA_INPUT before SELECT."
CALL FUNCTION 'CONVERSION_EXIT_ALPHA_OUTPUT'
  EXPORTING
    input         = gv_deldoc
IMPORTING
   OUTPUT        = gv_deldoc
SELECT vbelv posnv
    FROM vbfa
    INTO (l_vbelv,l_posnv)
     WHERE vbeln = gv_deldoc
       AND posnn = gv_posnr.
READ TABLE tbl_out INDEX 1.
  IF sy-subrc = 0.
    MOVE l_vbelv TO tbl_out-value.
    MODIFY tbl_out INDEX 1.
  ENDIF.
  READ TABLE tbl_out INDEX 2.
  IF sy-subrc = 0.
    MOVE l_posnv TO tbl_out-value.
    MODIFY tbl_out INDEX 2.
  ENDIF.
