Each line in a credit note may contain a reference to the relevant order line in the order that is identified on the document level in the credit note. If the creditnote contains several orders, the order reference is given at the line level only. The order reference at line level must refer to both the order and the actual orderline. The syntax for specifying this should be agreed between the parties. Recommendation: Ordernumber##Order line number
