Hi sap Memebers,
I want to change the valuation class of a material. There is currently no stock for that material but there is one purchase order for which the Goods have been received and invoice has also been posted. The delivery completed check has also been marked for that PO in the item details on the delivery tab page. PO status in the header shows " still to be delivered quantity 0 ". when i attempted to save the material master record after with a changed valuation class it showed me an error and the same po number in that error that the PO exists for the material.
What should i need to further check and what to do in order to change the valuation class.
Regards,
Ahsan Anwar
