PO validating while creating...

Former Member — Tue, 30 Sep 2008 11:39:27 GMT

Hi All,

I need to validate some item level data with the header data, So i wrote the code in User Exit. Its validating well, but if i press save button its simple asking a dialog and the PO is getting saved when i have errro also.

i have tried EXIT_SAPMM06E_007, EXIT_SAPMM06E_006 and EXIT_SAPMM06E_012 also. In call cases, its validating properly with throwing a message. But i am able to save...

can you please let me know your views on this.

Thnks,

Raghu Posani.

Hello Raghu

When you look through the signatures of the exit-fm's you have mentioned then you see that there is no parameter available to send back an "error flag" to the main application.

I am not very familiar with this user-exit function group but if you have BAdI ME_PROCESS_PO_CUST available on your system you can easily implement your logic in interface method IF_EX_ME_PROCESS_PO_CUST~CHECK, e.g.:


METHOD if_ex_me_process_po_cust~check.
* define local data
  DATA:
    lt_items      TYPE purchase_order_items,
*    ls_item       LIKE LINE OF lt_items,  " alternatively
    ls_item       TYPE purchase_order_item,
*
    ld_netwr_sum  TYPE netwr,
*
    ls_header     TYPE mepoheader,
    ls_detail     TYPE mepoitem,
    lt_details    TYPE tab_mepoitem.


"  check ( im_hold = 'X' ).  " hold purchase order



* Get the order items
  lt_items = im_header->get_items( ).

  REFRESH: lt_details.
  LOOP AT lt_items INTO ls_item.
    ls_detail = ls_item-item->get_data( ).

    ADD ls_detail-netwr TO ld_netwr_sum.  " Total of net price
  ENDLOOP.

* Check condition
  IF ( ld_netwr_sum > 1000 ).
    MESSAGE 'Net price > 1000 => create purchase requisition' TYPE 'E'.
    ch_failed = 'X'.  "
  ENDIF.


ENDMETHOD.

The "error flag" for the main program is CH_FAILED. If this CHANGING parameter is set CH_FAILED = 'X' the PO cannot be saved.

Regards

Uwe

Dear Uwe,

Thanks for the beautiful example...

But when i am trying to execute the below code with warning message, the warning message is not populating. Can you please tell me, why iam unable to display the warning messages??


    SELECT SINGLE *   FROM marc
                          INTO wa_marc
                     WHERE matnr = ls_detail-matnr
                        AND   werks = ls_detail-werks
                        AND   ekgrp = ls_header-ekgrp.
      IF sy-subrc NE 0.
        +*MESSAGE W072(zmm) WITH ls_detail-ebelp.*+ 
      ENDIF.

Thnks,

Raghu Posani.

Hi raghu,

Try issuing an Error Message instead of Warning.

Then why you have enclosed message statement with +* ?

Try removing that and try.
