When an invoice references items that have been delivered with separate dispatches, the references should be provided on the line level using the DespatchDocumentReference element.

When the invoiced quantity of an item has been delivered in more than one dispatch, the invoice must have separate lines for each dispatch. When dispatches are referenced on line level, you cannot have a document level reference.

Use the DespatchDocumentReference element to model this information at the Document level.

Use the DespatchLineReference subelement of the InvoiceLine element to model at the line level.
