Allocation Against Future Receipts 
When you use order allocation run (ARun), you can allocate future receipts to sales orders and stock transport orders. You can reserve stock from a future receipt to ensure that you will have the stock ready for the orders once the goods are received. In this way, the stock purchased for a specific customer or order is reserved for that customer or order only, even before the stock is received. Based on stock reservations, the committed deliveries to customers are fulfilled.
ARun allocates stock to the following types of future receipts:
Integration
All functions and features in ARun treat future receipts as if they were unrestricted stock, with the exception that the future receipt allocations can only be given the status Reserved (R). This status cannot be changed to Fixed (F).
Features
The system uses the following approach while allocating stock against future receipts:
Based on the Customizing settings, the system uses a best match strategy (dynamic stock prioritization) to match purchase orders or notifications and requirements. During the allocation process, the system runs a date validity check. This ensures that the incoming stock from purchase orders fall within the timelines of the assigned sales and stock transport orders.
ExampleCustomer A has an order for 100 pieces. The purchase order created for this order should have a goods receipt date that is prior to the confirmed delivery date of the sales or stock transport order. The system performs this check before the allocation process. Future receipts which do not fall within the timelines of the order are ignored for the current requirement that is being checked; however, they will be considered for other requirements which fit the date constraints.
End of the example.The release rule calculates the Reserved (R) status based on unrestricted stock.
ExampleYou have an order for 100 pieces with an 80% release rule. If an assignment achieves 80% fulfillment from a purchase order (future receipt) and 20% from unrestricted stock, all assignments are set to the status Reserved (R) .
Conversely, if you have 80% fulfillment from unrestricted stock and 20% from a purchase order, the assignment using physical stock is set to the status Fixed (F) because the release percentage is over 80%. However, the second assignment using the purchase order retains the status Reserved (R).
