Order Allocation Run 
Order allocation run (ARun) ensures that stock is assigned to orders according to the changing requirements in fashion. The special situation in the fashion industry requires an optimization of the assignment of existing stock to open requirements. In a stock shortage situation, order allocation run ensures an optimal assignment of stock to the open requirements and distributes the stock currently available to the respective sales orders or stock transport orders (STO) according to certain calculation logic at a specific time. If the ordered quantities are larger than the available stock, you can use ARun to achieve the best level of customer satisfaction under the given circumstances in your business. You can use the order allocation run Workbench to view and correct results of allocation if required.
Order Allocation Run Process Flow
Features
You use ARun to ensure that specific stock is assigned to an order and is not consumed by any other order.
You can choose articles for which you want to carry out an order allocation run before the delivery of the stock. You can make this setting in the Logistics: DC Fashion tab of the article master using the transactions MM41,42,or 43. You can deactivate this feature if you do not want to carry out an allocation run for an article at a plant level. The allocation type always determines the allocation run. The allocation type forms a framework and contains all allocation rules and checks that have been defined for a certain business process.
In the fashion industry, there is a difference of several weeks or months between the date of order creation and delivery date of goods to the customer. During this time period, the quantity of the ordered material or the available stock can be reduced for various reasons. The ARun tool helps you decide how this insufficient quantity should be distributed among the existing orders.
