You may agree to compensate a customer by allowing them to return a sold item against a sales return order. When you invoice the sales return order, you may then want to revalue the item at the unit cost that is connected to the original sales entry. (The program will, by default, value the item according to the current unit cost except in the case of a fixed application.)
At this point, you have shipped the item to the customer.
Create a sales return order for the customer.
Enter a line for the returned item.
In the Appl.-from Item Entry field, click the AssistButton to the right and select the number of the original sales entry number. This links the sales return order to the original sales entry and ensures that the item is valued at the original unit cost.
