Transactions that affect on-hand quantities affect the available quantity. Quantity information is vital in the day-to-day management of inventories. The item availability details help you understand current and future needs. The JD Edwards EnterpriseOne Inventory Management system determines the availability of an item by subtracting outbound quantities from the sum of inbound and on-hand quantities. You must define how you want the system to calculate item availability for each branch/plant by using the Branch/Plant Constants program (P41001). Item availability affects how the system calculates back orders, cancellations, and customer delivery times. 

You determine style item availability using the Style Item Availability program (PCW05). You can view a style item from the style item root level 0 to the child level item definitions. You can also view style item availability at each level of the item hierarchy in a matrix or tree view.
