Exchange of Data Between Sales Order and Assembly Order 
If dates or quantities are changed in the sales order, these changes are automatically transferred to the order created for the sales order. Conversely, changes to dates or quantities in the orders are also transferred back to the sales order.
For example, for the assembly order it works as follows:
- The material provision date and the order quantity are copied from the sales order to the assembly order.
- The manufacturing costs, the available quantity (if an availability check is carried out) and the confirmed date are copied back from the assembly order to the sales order.
