Quantity Reserve: The inventory reserved from Quantity on Hand for a product on an order. Reserved Quantity is set at both the Product Level and at the Warehouse Level. Any order pulled into SalesWarp from a storefront, or created in SalesWarp has the inventory required to fulfill that order reserved at the Product Level. The product level inventory represents all product available for sales from all warehouse locations. The Quantity Reserved is updated at the Warehouse Level only after payment has been captured. The inventory available for sale (Available to Promise) is pushed to any storefront where that product is available for sale based on the Available to Promise inventory shown at the product level.
Available to Promise = Quantity on Hand - Reserved Quantity
