For stock items, the system calculates availability status based on the availability calculation rules, which you define on the Availability Calculation Rules (IN201500) form. To specify how the system calculates availability for particular items, you assign the availability calculation rules you have created to particular item classes on the Item Classes (IN201000) form. By default, each item of this item class is assigned this rule. You can override the default availability calculation rule for each particular stock item on the Stock Items (IN202500).
