Is it possible to create 2 inbound deliveries with the same ASN number in SAP EWM?

by Vasilii Kharitonov

Here we will look into the case where the same supplier sends us 2 deliveries with the same ASN (Advanced Shipping Notification) numbers. Can we process them in SAP EWM? Is it possible to control possibility to process them in standard SAP?

In some cases we want to forbid such processing, as the same document could be processed twice in case of human mistake or our system landscape doesn’t support having 2 documents with the same external identification.

It allows you to manage the uniqueness of the ASN at the level of the level of Process profile (which in turn is assigned to EWM Delivery Type). There are following options present:
