Batch Classification characteristics value update during COR6/COR6n

Hi,

I have setup batch creation at process order release, but when I am doing COR6,COR6n not able to to update characteristic value in batch classification is there any way to achieve this.

If I do GR via migo then i can update it there or manually using MSC2N afterwards.tried fm suggested EXIT_SAPMM07M_004.

Pls guide if its possible or not via cor6/cor6n.

Thanks in advance
