Sorting Warehouse Inventory Items

I’m trying to make my stock take as easy as possible for the staff. My current problem is this… In Main menu -> Warehouse. I would like to only show Inventory that is listed on the specific Warehouse.

e.g Food items under food warehouse and bar items under bar warehouse, but mine shows all inventory items under all warehouses.


Warehouse code is for grouping the items inside the Warehouse screen.
Warehouse is where the item belongs if you have more than one warehouse.
