Demand

Demand calculations include component requirements, flow requirements, transfer orders, offset releases, part/delivery points, and sales orders.  Transfer orders are included if they have a relief code of M.  (The sales order planning flag refers only to customer orders, not transfer orders).  The sales orders are only included if they are sourced from manufacturing inventory (relief code = M) or they are sourced from distribution inventory (relief code D) at a manufacturing warehouse where the Sales Order Planning flag = Yes.   Customer orders sourced from distribution warehouses are never included in demand calculations within the manufacturing modules.  Sales orders, reserved inventory, and backordered inventory are considered in inventory status reports within Inventory Control and Order Processing.

Note that Master Scheduling and Requirements Planning treat planned and unplanned orders differently.  Planned orders are netted against forecast demand to determine whether actual or predicted demand is higher.  Unplanned orders are added to this net quantity to give the total demand.  Sales orders are labeled as planned or unplanned on the line detail screen.  Note, however, that the Sales Order Planning flag on the warehouse is still in effect--for sales orders that are not considered for planning, the Planned/Unplanned flag is irrelevant.

The following chart summarizes these relationships:
