When i try to to mark a Transfer order as "Shipped", I get this error:
A valid site transfer definition is required.

So what did I miss here?

Site Configuration --> Modules --> Inventory Management --> Transfer Definition

A Transfer Definition must be defined from a Site to every other Site, repeat for each Site to be able to transfer both ways.
