PO updation error for Requisitions (BANFN ) and Item (BNFPO) fields

Question

Dear Friends,
I am updating the Requisitions (BANFN ) and Item (BNFPO) fields via ME22N with using BDC for my PO.
But I am getting the following error when I have checked in my session .the error is
" PO item cannot be retrosp. converted into order-dependent 3rd-party item "
What does it mean?
Thanks,
Sridhar Reddy.

Hi Shanti,
What is the error message returned by the BAPI? you can have a look at the RETURN internal table, there you will find all errors passed by the BAPI.
To change the limit value of the PO you can use the following steps:
1. Declare the PO limit internal table:
    t_polimit        TYPE STANDARD TABLE OF bapiesuhc WITH HEADER LINE
2. Set the limit value of the PO:
    t_polimit-limit = the desired LIMIT_VALUE
    t_polimit-exp_value = the desired EXPECTED_VALUE
    append t_polimit.
3. Call the BAPI and pass the limit internal table
    CALL FUNCTION 'BAPI_PO_CHANGE'
      EXPORTING
        purchaseorder     = g_purchaseorder
        poheader          = wa_poheader
        poheaderx         = wa_poheaderx
        testrun           = g_testrun
        memory_uncomplete = g_memory_uncomplete
        memory_complete   = g_memory_complete
        no_messaging      = g_no_messaging
        no_message_req    = g_no_message_req
        no_authority      = g_no_authority
        no_price_from_po  = g_no_price_from_po
      TABLES
        return            = t_bapi_return
        poitem            = t_poitem
        poitemx           = t_poitemx
        polimits          = t_polimit
      EXCEPTIONS
        OTHERS            = 1.
     If you pass the correct header value for the PO it should be updated accordingly.
