We require to create a new Valuation class, and assign this to an existing material with open PO's and stock on hand,
SAP warns PO's are open when changing the material master.
The PO's are for projects ("Q" account assignment) and the projects are non-valuated. Is it still necessary to close the PO's in this scenario as the Goods receipt account posting hits the project and not the stock account. Closing down PO's causes us great pain with suppliers etc.
