An allowance/charge percentage is present, so its base amount must be provided as well.
- Rule
PEPPOL-EN16931-R041— official EN 16931 / XRechnung rule- Severity
- error
- Detected by
- tier 3 — KoSIT validator (authoritative)
- Reachability
- Triggerable from your request JSON (generate & validate)
The request schema allows amount + percent without base_amount; the serializer then writes a percentage without a base, which this rule rejects.
How to fix it
Set the allowance/charge base_amount, or remove the percent.
