Are you looking for material on setting up and using the optional WAREHOUSE feature in Sage X3 or information on managing stock storage location features in Sage X3?

I THINK most of the information is in the course material from Sage University.   

There is a section on Warehouse set up and usage in the Beyond the Basic distribution course manual which i believe is also used in the bootcamp.    

Sage u's "Sage ERP X3 Inventory Distribution - Fundamentals" has a section on Locations but RKL has a nice article on it too below.  

his was posted by Frank Bernal several years ago...

Warehouse management - Any suggestions? - General Discussion - Sage X3 - Sage City Community

Joel published this. Which is about LOCATIONS put away but has warehouse selection too.  . 

What is Put-away plan and how to process it? - Sage X3 Support - Sage X3 - Sage City Community

RKL published a paper on "Setting up Location Types in Sage X3"
