What this rule requires
Rule DE-R-015 is a fatal Peppol rule. If both the supplier and customer country are Germany (DE), the invoice or credit note must contain a cbc:BuyerReference element (BT-10) with a text value that is not empty or only whitespace. The test requires a cbc:BuyerReference whose normalized string is non-empty.
How to fix
Add a cbc:BuyerReference element as a direct child of the Invoice or CreditNote root and give it a non-empty value, for example a purchase order number or other reference. If the element is already present but empty or only whitespace, populate it with the buyer reference.
