The open sales order value is the value for which customer orders were recorded, but no delivery was yet made. Similarly, the quantity is the order quantity for which orders have been recorded, but again no delivery was yet made.

Updating the key figures for the open sales order value and open sales order quantity is influenced by two events:

• The open sales order value, i.e., the open sales order quantity increases when customer orders are recorded.
• The open sales order value, i.e., the open sales order quantity is reduced when deliveries are recorded which refer to the customer orders.

In an ideal case, the open sales order value, i.e., the open sales order quantity is always completely reduced through deliveries.

There are always two different update rules in the update definition for the open sales order values/open sales order quantity. An update rule describes the set up of the open sales order value, i.e., the open sales order quantity. The second update rule describes the reduction of open sales order value, i.e., the open sales order quantity by the corresponding deliveries.
