What's the difference between nettable and nonnettable quantities for on-hand quantity and availability calculations?

Nettable quantities are available for fulfilling demand. The on-hand quantity and available quantity calculations on the Review Item Supply and Demand page include nettable quantities. If the subinventory, locator, and lot for a quantity are nettable for their associated material statuses, then the item quantity is also nettable.

Nonnettable quantities aren't available for fulfilling demand. The on-hand quantity and available quantity calculations on the Review Item Supply and Demand page don't include nonnettable quantities.
