Enhancement of MIGO

Question

Hi all,
I have a requirement to post  an accounting entry into 2 gl accounts when a migo (Good Reciept [both posting and rversal] ) is done on a particular type of purchase order (this is apart from the normal ones which have been added by the MM person). This I did through a BDC program on F-02 and added it through an enhancement. But now, the requirement is that the DOCUMENT NUMBERs of the normal accounting entry and that of my new posting should be same so that when they click on accounting documents for that particular migo, it should display all the postings; both the normal one and that which i have just added. I have tried all i could but have not gotten a right way to do this.
Please any body in the house with any sound advise on how to do this?????

Answer 1

Of course, you realize it is not possible to get two accounting documents with the same document number, you need two different accounting (FI, BKPF) documents referencing the same material document. (MM, MKPF)
In your batch-input (BAPI would be better) give reference to the material movement document:
- AWTYP = 'MKPF'
- AWKEY = MKPF-BELNR + MKPF-GJAHR
Sample: (in an implementation of MB_DOCUMENT_BADI~MB_DOCUMENT_BEFORE_UPDATE "Exit after Writing a Material Document. Not in 'update task'")
  DATA : lv_awtyp TYPE awtyp,
         lv_awkey TYPE awkey,
         ls_mkpf_awkey TYPE mkpf_awkey.
    WRITE 'MKPF' TO lv_awtyp.
    ls_mkpf_awkey-belnr = i_mkpf-mblnr.
    ls_mkpf_awkey-mjahr = i_mkpf-mjahr.
    WRITE ls_mkpf_awkey TO lv_awkey.
      CLEAR ls_bdcdata.
      ls_bdcdata-fnam = 'BKPF-AWTYP'.
      ls_bdcdata-fval = lv_awtyp.
      APPEND ls_bdcdata TO lt_bdcdata.
      CLEAR ls_bdcdata.
      ls_bdcdata-fnam = 'BKPF-AWKEY'.
      ls_bdcdata-fval = lv_awkey.
      APPEND ls_bdcdata TO lt_bdcdata.
