The Location above is a UBL-2.1 path, and no UN/CEFACT-CII path for this rule is published here; Fix and Fix (Deutsch), verbatim from remediation_catalog.json and not reworded here; the UN/CEFACT-CII binding of this rule is differentially proven against the official KoSIT XRechnung 2.5.0 (XRechnung 3.0.2) Schematron.
Where to check the fix: paste the corrected invoice into the browser validator at /einvoice/validate/ — it runs this same engine locally in your browser, with no upload, and stops reporting PEPPOL-EN16931-R121 once the edit lands.
Korrektur prüfen: Laden Sie die geänderte Rechnung in den Browser-Validator unter /einvoice/validate/ — er führt dieselbe Engine lokal im Browser aus, ohne Upload, und meldet PEPPOL-EN16931-R121 nicht mehr, sobald die Korrektur greift.
