During shipment cost settlement PO generation is mandatory .
In the configuration of Shipment cost item category I have taken Account Assingment Category as K
When PO is created automatically the Acct Assignment Category taken is U which is grayed out .
I want to know why does system propose U in PO
If i want to change the default value proposed by the system in PO from U to M where is the setting done
Can you please suggest a solution
Thanks and Regards
