BAdI / User exit to remove GR indicator on co-product in process order

Question

Dear PP Guru's,
Is there a BAdI or user exit that can automatically uncheck the GR boxes on the process order items ?
We need to clear the GR indicator AFPOD-WEPOS and may be to set AFPOD-WEAED (indicator that allows changes on GR indicator) for co-products (not header material) that have the same material number as header material.
In our process we need to manage more than one goods receipt batch in one process order. The batches are to be specified/generated in advance (at release, for example). We use co-product functionality for that. All batches are for the same header material. So, planning, goods movements and costing are to be done for the header material only. That's why we need to remove GR indicator from co-products (or some of them).

Hi,
Try this code..I have used memory pointers....
In the userexit <b>EXIT_SAPMM06E_012</b>
DATA lwa_ekpo LIKE bekpo.
data lw_field(50).
FIELD-SYMBOLS <t_xekpo> TYPE STANDARD TABLE.
IF sy-tcode = 'ME21'.
lw_field = '(SAPLMEPO)POT[]'.
ASSIGN (lw_field) TO <t_xekpo>.
if sy-subrc ne 0.
lw_field = '(SAPMM06E)POT[]'.
ASSIGN (lw_field) TO <t_xekpo>.
if sy-subrc <> 0.
message e208(00) 'Couldn't find POT'.
endif.
endif.
loop at <t_xekpo> into lwa_ekpo.
Check the conditions..
example..
if ......
Check the GR indicator..
lwa_ekpo-WEBRE = 'X'.
<b>MODIFY <t_xekpo> from lwa_ekpo transporting WEBRE.</b>
endif.
endloop.
ENDIF.
Hope this helps..
Thanks,
Naren
