When using inventory statuses in warehouse management it should be easy ways to change inventory statuses for current stock.
The periodic job for changing statuses is often used:
Warehouse management/Periodic tasks/Inventory Status Change
When quantity on stock is dependent on the inventory status, for example if a tube(location) contains 100ul or above the inventory status should be "big tube" but when the tube(location) is less than 100ul it should have inventory status "small tube"
This means it should be able to filter on physical inventory in this job to be able to automatically update the inventory status depending on quantity.
Not it is possible to filter on reserved quantity, available quantity, CW physical inventory but for some reason not physical inventory.

So Physical inventory needs to be added in the filter.
