Dear Abhijeet, I find your entry very clear and helpful. I hope you can help me sort out an issue I have in my AX R3 solution. Our user created a PO and we wish to cancel the receipt and the PO, but the system is giving me the following errors when we click on Cancel inside the Product receipt: Physical updating quantity in the inventory unit PIECE must be other than zero. Physical remaining quantity in the inventory unit PIECE must be other than zero. When I try to look for the inventory transaction, there is NONE. The status of the PO is Received. We are hand-tied. Any suggestion? Any comments will be most appreciated.
