FI MM integration

Hi,

My system has wrong account assignment for Movement type 653. So wrong account is been picked up while return of finished product occurs.

I understand that in OBYC I need to make change in GBB against Valuation class 7900 but I am not sure which General modifier so select.

I am confused between VAY, VAX, VKA. I am not able to decide from their descriptions.

Kindly help me.

Thank you.
