In addition to the stock types that are managed in the material master record, the system can display other stocks, which you can use various functions to display (see section Reporting in Inventory Management ). The list below contains examples of these dynamically calculated stocks:
Dynamic stock that is calculated by MRP (with respect to the time axis) taking any receipts, issues, and the current available stocks into account. You can define how MRP is set up under the plant parameters in Customizing for MRP (see also Availability Check ).
Sum of all quantities of a material that are reserved for withdrawal. Reserved stock is not available from the point of view of MRP, but for Inventory Management it still counts as unrestricted-use stock.
Sum of all quantities whose receipt has been planned with reservations. Planned receipts are already available from the point of view of MRP, but for Inventory Management they do not yet count as unrestricted-use stock.
Sum of all outstanding PO quantities for a material. The open PO quantity increases available stock in MRP, but it does not increase unrestricted-use stock in Inventory Management.
Sum of all outstanding order quantities for a material. The open order quantity increases available stock in MRP, but it does not increase unrestricted-use stock in Inventory Management.
The total of all quantities of a material that was delivered for purchase orders and accepted conditionally. Goods receipt blocked stock is not valuated and does not count as unrestricted-use stock.
Sum of all current deliveries to customers for which goods issues have not yet been posted. Like reserved stock, stock scheduled for delivery is usually not available from the point of view of MRP, but it counts as unrestricted-use stock for Inventory Management.
