field3 rules
Every EN 16931, Peppol and XRechnung rule that constrains BT-37. 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-DE-3 | fatal | Das Element "Seller city" (BT-37) muss übermittelt werden. |
| DE-R-003 | fatal | The element "Seller city" (BT-37) shall be provided. |
| IT-R-003 | fatal | BT-37 (Seller city) - Italian suppliers MUST provide the postal address city - I fornitori italiani devono indicare la città di residenza. |
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.
