What's an item subinventory?

An item subinventory is an association of an item with a subinventory that's created when you add an item to a subinventory.

You might want to restrict an item to a subinventory to store it with other items that have a similar size, volume, weight, specific storage requirement such as refrigeration, or the type of labor and equipment used to create the item. You also add an item to a subinventory to either perform min-max planning on the item, or include the item in an ABC classification set for ABC analysis.
