Hi Les,
in R/3 Tcode CMOD and create, if does not already exist a project, for example ZBW1 (is simply a definition). Then enter in Components of the project selecting the corresponding flag and then select EXIT_SAPLRSAP_002 Exit Function.
Then double click on the word ZXRSAU... at the right of word INCLUDE.
In the next screen you introduce your code.
Hereunder an example for vendor:
DATA: L_BIW_LFA1_S LIKE BIW_LFA1_S,
      l_tabix LIKE sy-tabix.
CASE i_datasource. <i><b>(this is always necessary)</b></i>
WHEN '0VENDOR_ATTR'.
   LOOP AT i_t_data INTO l_BIW_LFA1_S.
     l_tabix = sy-tabix.
     SELECT XEGLD FROM T005
             INTO V_XEGLD
              WHERE LAND1 = l_BIW_LFA1_S-LAND1.
       IF V_XEGLD = ' '.
          l_BIW_LFA1_S-ZZXEGLD = 'E'.
         ELSE.
          IF l_BIW_LFA1_S-LAND1 = 'IT'.
             l_BIW_LFA1_S-ZZXEGLD = 'I'.
            ELSE.
             l_BIW_LFA1_S-ZZXEGLD = 'C'.
          ENDIF.
       ENDIF.
     ENDSELECT.
     MODIFY i_t_data FROM l_BIW_LFA1_S INDEX l_tabix.
    ENDLOOP.
ENDCASE.  <i><b>(this is always necessary)</b></i>
Ciao.
