The ABC class code classifies items by their importance in a manufacturing system and determines count frequencies. Class A items are counted more frequently than class B items. Class B items are counted more frequently than class C items.

Use Item Master Maintenance (1.4.1) or Item Inventory Data Maintenance (1.4.5) to assign ABC class. You can also have the system calculate it automatically by running Item ABC Status Report/Update (1.5.9 or 3.6.3; 1.5.33 or 3.6.27 for enhanced .NET UI version). Optionally, that function lets you exclude items based on item status code.

For each ABC class, assign item tolerances (percentage and amount) in Inventory Control. When count discrepancies arise, the system checks item tolerances by class.
