Cost Object require at the time of PGi
I have a question:
We have created a Delivery and at the time of doing PGI we are getting error message GL Account requires a CO Object.
I know the solution of this issue, to maintain the Cost Center in OKB9 for the cost Element.
My Query is is it necessary to create Consumption GL Account as Cost Element, also why do not we create Cost Element for for COGS Account.
