FACTS has been enhanced to implement the Advanced Inventory Management (AIM) procedures as defined by Grant Howard. The new AIM model includes differences in usage storage, definition of Order Point (OP) and Line Point (LP) calculation, and required changes to the IC, MC, PO, SA and SO modules. Further capability for temporary Line Point, identification of similar items to purchase, and sales order line factors were also added to the solution. The advanced inventory enhancements provide new functionality in FACTS. The Purchase Order module changes are covered in this section.
