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.
In other cases suppliers can’t ensure to provide a unique number each time, e.g., their numbering is based on day and month, but repeats each year. Therefore, it is important to have control over ASN uniqueness.
In SAP EWM, a specific setting controls the uniqueness of ASN. You can locate this setting by navigating the following path: Extended Warehouse Management -> Cross-Process Settings -> Delivery - Warehouse Request -> Process Management and Control -> Define Process Profile for Document Header. 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:
System Default
. The defaults are different per different
systems, please check what is set for your system to undestand the behaviour:
Check if ASN number is Unique
. The system will check that the ASN number is unique per ship-from party and business system. If it is not unique the delivery will be blocked from processing.Do not check if ASN number is Unique
. The system will not
check if ASN number is unique. You can easily receive 2 different deliveries
with the same ASN number from the same supplier.
