The following columns are added to the inventory grid:

Uom2 Qty Warehouse
This is the quantity for the second UOM that is in stock. In case it is a catch weight item, this will be the actual weight. If it is an item with a UOM2, but no catch weight, this will be the calculation of UOM2 based on the default ratio between both UOM.

Uom2 Qty Confirmed
This is the quantity for the second UOM that is committed. The calculation of UOM2 based on the default ratio between both UOM.

Uom2 Qty Ordered
This is the quantity for the second UOM that is ordered. The calculation of UOM2 based on the default ratio between both UOM.

Uom2 Qty Available
This is the quantity for the second UOM that is available. The calculation is: (In stock + Ordered) - Confirmed

Note: The above listed UoM2 columns are filled in only when there is a UoM2 defined.
