What is DE-R-016?
DE-R-016 is a fatal validation rule defined in the EN 16931 specification (DEU national rules). It validates the CityName element under Party > PostalAddress in the UBL invoice XML.
When this rule fires, the invoice is rejected by Peppol access points and never reaches the buyer.
Target path: //cac:AccountingSupplierParty/cac:Party/cac:PostalAddress/cbc:CityName
Why This Error Matters
Invoice will be rejected by German XRechnung validators. Germany has additional mandatory fields beyond EN16931 baseline, including seller contact details, complete addresses, and buyer reference (Leitweg-ID).
DE-R-016 is a hard failure — the invoice must be corrected and re-sent before it can reach the recipient.
Invoice Navigator can automatically correct this error in your pipeline. The fix is applied with full audit evidence, so your compliance trail remains intact.
