Purchase Suggestions for Two "Digital Warehouses" in one "Physical Warehouse"

Actually,

I’m looking at the settings for part and warehouses, there aren’t inventory min and max settings for the individual warehouses. Those settings that are there are for kanban replenishment. That means you’ll be purchasing to the default warehouse, then doing moves to replenish the other warehouses or bins. You have an overall min max, and a lesser min max in each location.

So the multiple part numbers is the only way to actually set that up.
