Me21N transaction Vendor check

Question

Hello All,
While creating a PO in Me21N, Vendor should be validated. If the check fails, PO should not be created and the error message should be displayed to the user. I've used User-exit EXIT_SAPLEBND_002 & EXIT_SAPMM06E_012. Upon check failure, error message is being raised from both, along with a pop-up box with Save, Edit and Cancel buttons. Incase the user selects "Save", PO is created. I do not want this pop-up box to be displayed or do not want the user to have a choice of saving the PO when a error message is raised.This pop-up box is being raised by the standard SAP program.
Is it possible to supress this window from showing-up? Or am I using the wrong exit? I tried using BADI method IF_EX_ME_PROCESS_PO_CUST~PROCESS_HEADER. But this is getting not triggered.
Thanks.

Hello Sakthi,
I have added my validation in User-Exit "EXIT_SAPMM06E_012".
Below is the sample code:
  IF sy-tcode = 'ME21N' OR sy-ucomm = 'MESAVE'.
    IF i_ekko-bsart = 'XYZZ' and i_ekko-lifnr = 'P123456'.
           MESSAGE e000(zm001) DISPLAY LIKE 'E' WITH 'Vendor' i_ekko-lifnr 'is not allowed for Document Type' i_ekko-bsart.
          RETURN.
     ENDIF.
ENDIF.
In place of "MESSAGE e00......" you could use below macro :
mmpur_message_forced 'E' 'ZM001' '000' 'Vendor is not allowed for Document Type'.
This macro is used to give soft error message. I tried with "A" instead of "E" message type too and it didn't work. It will trigger a pop-up window with "Save", "Edit" and "Cancel" buttons. If user clicks on "Save", it would create a PO. In my case I did not want the PO to be created, incase validation fails. So I did not use macro. My sample code triggers a pop-up window with "Hold", "Edit" and "Cancel" buttons. Hence a PO is created with Parked status.
Thanks,
