Definicja difference calculation
The billing of invoice correction items.
During difference calculation, the system generates a new billing document with an item pair. The item pair is made up of a new, correcting billing document item with the current data, and an offset billing document item that was corrected. The offset item is a copy of the old billing document item that was to be corrected, but with the debit/credit signs (+/-) switched for the quantity and amount. When added together, the quantity and amount in this item pair is equal to the difference between the old and new data.
