Unable to update EKPO field at time of save in ME32k

[former_member185116]

Hello all,

I want to update Tax Code field (in me31k and me32k) while saving ,

for this i have used exit EXIT_SAPMM06E_012 ,

but its not updating the Tax code,

below is my code,

if sy-tcode eq 'ME32K' or sy-tcode eq  'ME31K'.
  if i_ekko-bsart is NOT INITIAL.
    select SINGLE * FROM ZMM_AGMT_TAX INTO wa_agmt_tax WHERE zbsart eq     i_ekko-bsart.

    if sy-subrc = 0.
         lv_agmt_tax = wa_agmt_tax-zmwskz.
      endif.
      if tekpo[] is NOT INITIAL.
           loop at tekpo into wa_tekpo.
             wa_tekpo-mwskz = lv_agmt_tax.
             MODIFY tekpo FROM wa_tekpo TRANSPORTING mwskz.
           endloop.
       endif.
    endif.
endif.

where in ZMM_AGMT_TAX we are maintaing some tax codes based om agmt type BSART.

thanks in advance..

This Exit FM is only provided for check, with a simple 'where-used' search you will note that it works with a local copy of data, so don't expect that changing those data will be copied back to main program, only the header customer fields can be changed (changing parameter c_ci_ekko)

Alas, no BAdI seem available (read 2300802 - ME_PROCESS_OUT_CUST is not called in ME31L/ME32L/ME31K/ME32K.) only the exit you found and it's only purpose is check, so you should look for some implicit enhancement for example.
