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 CEN EN 16931 1.3.16 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 BR-47 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 BR-47 nicht mehr, sobald die Korrektur greift.

The same invoice, failing and fixed

Neither block below is hand-written, and neither is an illustration: both are cut verbatim out of corpus/cen-en16931/test/Invoice-unit-UBL/BR-47.xml, the vendored unit test the CEN EN 16931 project ships for this rule. The people who wrote the Schematron wrote these two documents and labelled them <error>BR-47</error> and <success>BR-47</success>. They are published here only because this engine agreed with that labelling: it reported BR-47 for the first document and did not report it for the second, under --profile en16931.

Read that pair of lists honestly. A unit case is not a complete invoice: the upstream suite strips the document down to the elements this rule reads, so the engine also reports every mandatory element the fragment leaves out — 15 other rule ids here. Those are noise for this page. The signal is the difference: BR-47 is reported for the failing document and gone for the corrected one, and it is the only id that moves.

Reproduce it yourself: save the failing block as invoice.xml and run einvoice validate invoice.xml --profile en16931 --format json, or paste it into the browser validator, which runs this same engine locally with no upload. Then apply the edit the passing block shows and run it again.
