group of fields1 rules
Every EN 16931, Peppol and XRechnung rule that constrains BG-8. If one of them fails, the others are usually worth a look — a wrong value in one field tends to break several checks at once.
| BR-10 | fatal | An Invoice shall contain the Buyer postal address (BG-8). |
Nothing is stored, and the whole invoice is checked, not just this rule. A PDF only works if it is Factur-X / ZUGFeRD — a PDF with the invoice XML inside it.
