I'm facing the following issue :
I'm creating a purchase order (tcode ME21N) for a material types ZSER.
The system requires for this material types to use an account assignment category.
The cost center is automatically filed with the value defined in OKB9
The issue is that we want to use the account assignment detail 3 in OKB9 to get the cost center from the profit center of the material used for the PO
When we use this option in OKB9 the cost center is not automatically populated anymore in the PO.
Any idea why we could not get the cost center automatically populated when we use the account assignment detail 3 in OKB9?
