Each transaction that affects an item’s Quantity On Hand or Quantity On Order is reflected in real time.  This applies to Purchasing, Receiving, Sales, Inventory Adjustments, Credit Returns, Vendor Returns, and Scrappage.  Inventory Status is continually updated as orders move through the system.  When an order is placed it goes from Available to Committed and when an Invoice is produced after an order is picked, it is subtracted from the Quantity On Hand.
