We want change Valuation Class of a particular material.
To do so we closed all open POs using Delivery complete indicator in ME22n.
Also we cant delete this PO Line Item it gives warning as Quantity Delivered is smaller than Quantity Ordered.
Stock is also zero, as we transferred all the stock to another Material Code.
But when we tries to change Valuation Class it gives error PURCHASE ORDERS ALREADY EXISTS
Due to this unable to change valuation class.
Thanks & Regards
