Official xrechnung source, version 2.6.0 / XRechnung 3.0.2. Apache 2.0; sources, licences and notices. Syntax and business checks are separate; this is not certification.

Reproduced failure and correction

Tested on 2 November 2026 with the production SaxonC-HE 13.1 / saxonche 13.1.1 engine, xrechnung mode, UBL. The XSD passes; the report then contains PEPPOL-EN16931-R120. Restoring this fragment makes the complete original invoice pass the selected checks.

[PEPPOL-EN16931-R120]-Invoice line net amount MUST equal (Invoiced quantity * (Item net price/item price base quantity) + Sum of invoice line charge amount - sum of invoice line allowance amount

Additional triggered rules: 0. None. Counts include distinct error and warning codes; the target code is excluded.

Precise mutated XPath: /*/cac:InvoiceLine[1]/cbc:InvoicedQuantity.

Calculation using this invoice

Line net amount shown: 100.00 EUR. Expected: quantity 2 × (net price 100.00 / base quantity 1) + line charges 0.00 − line allowances 0.00 = 200.00 EUR. The absent price base quantity defaults to 1. Difference: 100.00 EUR, exceeding the pinned tolerance. Round the line result to two decimal places; restoring the original quantity 1 gives 100.00 EUR.

The context shown is part of a complete invoice; it is not a standalone invoice. Mutation: value at /*/cac:InvoiceLine[1]/cbc:InvoicedQuantity. The passing baseline is validated with the selected pinned package. UBL examples use a controlled single-line adaptation of the official XRechnung example; the CII example uses the official EN 16931 baseline.
