We have a Sales Order for a customer. We have a receipt of the product for this customer that we then shipped out. We noticed an error so we deleted the Customer Shipment and we are now trying to back out the receipt. When we uncheck the Received All box and attempt to save we get the error: Cannot uncheck the received flag. Inventory has already been allocated to order XXX. When I look at Allocations for this part under Part Tracker there is nothing showing. Any ideas?
Is it Buy To Order? If so, have you tried Unpick Sales Order?
