Purpose
When you create a return with reference to a previous document, you must take copy rules into account for items determined in product selection.
Process Flow
You have already set the system to copy order items determined in product selection exactly as they are.
Note that the system does not carry out product selection in return deliveries, regardless of your settings. All entries are copied as they are from the return order.
Product selection functions are supported only in returns that are based on orders. There are no Customizing settings for product selection in billing documents. If you create a return in reference to an invoice, the system automatically copies all schedule lines. You must then manually delete items that you do not want. Additionally, the system does not copy quantities. These you have to enter manually in the return.There is no quantity correlation between main and sub-items.
