P.O line items change exit

Question

Hi All
Could any one let me know the user exit name used to modify the line items values of a P.O. in the transaction ME22N. I am using the exit EXIT_SAPMM06E_012. Its not changing the values of EKPO. Please suggest.
Thank You,

DATA: WA_ERNAM LIKE EBAN-ERNAM.
IF ( SY-TCODE = 'ME21' OR
     SY-TCODE = 'ME21N' ) AND I_EKKO-BSART = 'NB'.
  LOOP AT TEKPO.
    IF NOT TEKPO-BANFN IS INITIAL.
      SELECT SINGLE ERNAM
               FROM EBAN
               INTO WA_ERNAM
              WHERE BANFN = TEKPO-BANFN AND
                    BNFPO = TEKPO-BNFPO.
      IF SY-SUBRC = 0.
        TEKPO-AFNAM   = WA_ERNAM.
        TEKPO-ZREQUIS = WA_ERNAM.
       MODIFY TEKPO TRANSPORTING AFNAM ZREQUIS
                    WHERE BANFN = TEKPO-BANFN AND
                          BNFPO = TEKPO-BNFPO.
        MODIFY TEKPO INDEX SY-TABIX.
      ENDIF.
    ELSE.
      TEKPO-AFNAM   = SY-UNAME.
      TEKPO-ZREQUIS = SY-UNAME.
     MODIFY TEKPO TRANSPORTING AFNAM ZREQUIS
                  WHERE BANFN = TEKPO-BANFN AND
                        BNFPO = TEKPO-BNFPO.
    ENDIF.
  ENDLOOP.
ENDIF.
The above is the code i have written in EXIT_SAPMM06E_012 its not showing the changed values of AFNAM and ZREQUIS in EKPO. That is in ME21N while creating the P.O.
Please suggest.
