Can RejectFix repair this automatically?
RejectFix can report implemented checks and only offers a deterministic repair when the intended value is unambiguous. Business identifiers, dates, payment terms and accounting values must come from your source system rather than being invented.
Scope: This guide explains the official rule, but RejectFix is not the official OpenPeppol Schematron or an Access Point and cannot guarantee acceptance. Confirm the current requirement with your Access Point.
