D365 SCM Warehouse Only licensing requirement

Hi all,

If anybody has more insights on the D365 SCM Warehouse Management Only solution and it's licensing requirement, that would be great: Warehouse management only mode overview - Supply Chain Management | Dynamics 365 | Microsoft Learn. 

Eg. does the customer needs to pay regular SCM licenses with 20 seat minimum? (I expect so). 

Or, since it's only a part of the SCM module, are there some license exceptions? 

Cheers,

Martijn
