Need a badi or user exit to update numbers at level of Goods Receipt level

Question

Hi I need to update serial number based on combination of plant, company code and fiscal year while generating a Goods Receipt by using MIGO transaction code.
Step1) once run the MIGO transaction, here enter values of Purchase Order, Quantity, and delivery note and check the item ok check box for goods receipt.
Step2) Then check for any warnings and errors by clicking the check button/tabular
Step3) Finally post the goods receipt for the purchase order by clicking Post button/tabular.
Result:
Then system will provides the Material of Document number for the goods receipt of purchase order. That number like 5000000342.
Here client wants to put his number like V500000001.for one combination of plant, company code and fiscal year.
Example
Z TABLE AS LIKE BELOW COMBINATION
Plant                  company code             first no               end no               current no     FISCAL YR
7800/7801      2000                            V500000001      V599999999             
7802/7803      3000                            F500000001      F599999999         
7804                4000                            D500000001      D599999999         
Whenever end user generates a GR then System should display one of above number instead of systems generate value.
I have used to fix the issue badi> mb_badi_migo document_badi_update and user exit-> mb_cf001, mbcf0002 but not found the solution.
Please provide me needful information.
Thanks,

Hi
<b>Here is the sample code...</b>
method if_ex_mb_migo_badi~post_document .
  data: ls_migo_badi_example type migo_badi_exampl,
        lt_migo_badi_example type table of migo_badi_exampl,
        ls_extdata type migo_badi_example_screen_field,
        ls_xmseg   type mseg.
  field-symbols: <gt_extdata> type migo_badi_example_screen_field.
* Transaction MIGO will now post a material document.
* Any errors here MUST be issued as A-message (better: X-message)
* Copy data from material document into internal table
  loop at gt_extdata into ls_extdata.
    if g_cancel is initial.
      read table it_mseg into ls_xmseg
         with key line_id = ls_extdata-line_id.
    else.
      read table it_mseg into ls_xmseg
         with key smbln = ls_extdata-mblnr
                  smblp = ls_extdata-zeile
                  sjahr = ls_extdata-mjahr.
    endif.
    if sy-subrc is initial.
      move-corresponding ls_extdata to ls_migo_badi_example.
      move-corresponding ls_xmseg   to ls_migo_badi_example.
      append ls_migo_badi_example to lt_migo_badi_example.
    endif.
  endloop.
* The data from external detail screen can be saved now:
  check gt_extdata is not initial.
  call function 'MIGO_BADI_EXAMPLE_UPATE_DATA' in update task
    tables
      it_migo_badi_example = lt_migo_badi_example.
* The data from external header screen can be saved now:
  move-corresponding is_mkpf to gs_exdata_header.
  call function 'MIGO_BADI_EXAMPLE_UPDATE_HEAD' in update task
    exporting
      is_migo_badi_header_fields = gs_exdata_header.
endmethod.                    "IF_EX_MB_MIGO_BADI~POST_DOCUMENT
Hope this will help.
Please reward suitable points.
