Hi, I have a material (X) with a serial number (Y) in in customer consigned stock. Our user created customer return order (order type:RE) with no order reference and brought into unrestricted stock for same material(X) with same serial number (Y). The system allowed this. I am under the impression, it should not allow same material (X) with same serial number(Y) in stock more than once, it is a serial number duplicate situation. We have serial numbers defined at client level - unique number at client level. Am I missing some configuration or standard SAP (we are on ECC6.0) allows this? Appreciate your help.
