What is GR-R-009?

GR-R-009 is a fatal validation rule defined in the CIUS-GR (Greece) specification (GRC national rules). It validates the DocumentCurrencyCode element in the UBL invoice XML.

When this rule fires, the invoice is non-compliant and will be rejected by Peppol access points and national validation services. The sending system receives a rejection response and the invoice does not reach the buyer.

Why This Error Matters

Invoice will be rejected by Greek PEPPOL validation. Greek suppliers must be identified by TIN on PEPPOL.

GR-R-009 is a hard failure. Invoices that trigger this rule are rejected at the access point and never reach the recipient. In Peppol networks, this means your sending system receives an MLR (Message Level Response) with a rejection status. The invoice must be corrected and re-sent, adding delay to your payment cycle.

Invoice Navigator can automatically correct this error in your pipeline. The fix is applied with full audit evidence, so your compliance trail remains intact.
