Workflow triggers unwantedly

Question

Hi All ,
we are a strange issue in EC incoming Invoice workflow in SRM, descriptiojn is as follows
we have two workflow in our system for invoice one goes through approval and other auto approval , and on the SRM portal at header level in the basic data we have added two custom fields allow NON-PO invoice and Allow RE ,and implemented the doc_check_badi , now at the line item level if we do not give any PO refernce and check/post  then we get an error message saying the entrer PO and the status of the invoice to " to be corrected manually" ideally in the above case approval  workflow should not trigger , it sould only trigger when we tick the allow Non-po invoice check button , and it was working fine , but suddenly after patch upgrade the approval workflow triggers even if we do not tick the chck box at header level . Can anyone suggest did any thing go wrong in patch upgrade , I have checked all the conditions and linkages all are fine, but i guess some standard setting is missing which would have gone missing .

Dear all,
         Thanks a lot for reading my post with intention to answer.
         The issue is resolved now.
         The problem was at BAdI.To trigger the workflow with event CREATED for purchase requisition, BAdI named ME_REQ_POSTED needs to be used :
         Following coding is used for the same :
method IF_EX_ME_REQ_POSTED~POSTED.
  DATA: WA_EBAN TYPE EBAN.
  DATA L_S_EBAN TYPE UEBAN.
  DATA: OBJKEY TYPE SWEINSTCOU-OBJKEY .
  LOOP AT IM_EBAN INTO L_S_EBAN .
  ENDLOOP.
    IF ( SY-TCODE = 'ME51N' AND SY-UCOMM NE 'MECHECKDOC' ) OR SY-TCODE = 'ME52N'  .
      IF  L_S_EBAN-BSART = 'ZNB'.
        OBJKEY = L_S_EBAN-BANFN.
        SELECT SINGLE * FROM EBAN INTO WA_EBAN WHERE BANFN EQ OBJKEY.
        IF SY-SUBRC NE 0.
          CALL FUNCTION 'SAP_WAPI_CREATE_EVENT'
            EXPORTING
              OBJECT_TYPE             = 'BUS2105'
              OBJECT_KEY              =  objkey
              EVENT                   =  'CREATED'
             COMMIT_WORK             = 'X'
             EVENT_LANGUAGE          = SY-LANGU
             LANGUAGE                = SY-LANGU
             USER                    = SY-UNAME
*   IFS_XML_CONTAINER       =
* IMPORTING
*   RETURN_CODE             =
*   EVENT_ID                =
* TABLES
*   INPUT_CONTAINER         =
*   MESSAGE_LINES           =
*   MESSAGE_STRUCT          =
        endif.
      endif.
    endif.
   endmethod.
          I have missed the loop block.That's why the workflow was not triggering.
