Overview:

In this blog, I will attempt to explain how the availability group and ERP storage location are linked, as well as how the stock type is determined in the EWM inbound delivery. And this behavior is same for both S4hana Embedded EWM and Decentralized EWM system.

How does the inbound delivery get the stock type in EWM?

When a purchase order is created, the ERP stock type is displayed in the delivery tab.

Ex: Unrestricted, Quality, and Blocked stock

In the following PO, the stock type of item# 10 is unrestricted, and item# 20 in quality inspection.



When an inbound delivery is created in ERP (VL31N), it is replicated in EWM with the following stock types,


Item 10: Unrestricted in ERP & Stock type F1 in EWM


Item 20: Quality inspection in ERP & Stock type Q3 in EWM


According to the screenshots, it is clear now that system is assigning the stock type as follows,


















Item ERP stock type EWM stock type
10 Unrestricted F1-Unrestricted use in putaway
20 Quality inspection Q3-Stock in QI in putaway

The question here is, how does the system automatically assign these stock types? Check the following configuration,


Case:1 PO item 10 with Unrestricted in ERP,

When the inbound delivery gets transferred to the EWM system, it checks the table below and finds the non-location dependent stock type (NST) that is the ERP stock type in the EWM system.

We can see in the below table that for the warehouse KCWH, NST stock types of FF is there, and it is assigned with availability groups 001,002, and 0003.

But the system took only F1 in the inbound delivery as availably group 001 is assigned to the combination of plant and storage location of the purchase order.


Case:2 PO item 10 with quality inspection in ERP,

When the inbound delivery gets transferred to the EWM system, it checks the table below and finds the non-location dependent stock type (NST) that is the ERP stock type in the EWM system.

We can see in the below table that for the warehouse KCWH, NST stock types of QQ is there, and it is assigned with availability groups 001,002, and 0003.

But the system took only Q3 in the inbound delivery as availably group 001 is assigned to the combination of plant and storage location of the purchase order.


Conclusion:

I hope this blog explains how the EWM inbound delivery get the stock type with the required configuration and test cases.
