What does GR-R-008-3 mean? When Supplier is Greek and the INVOICE URL Document reference exists, the External Reference URI should be present

Why did my invoice fail GR-R-008-3?

When the supplier is Greek and an INVOICE URL document reference exists, the External Reference URI should be present inside it. The reference is only useful if it actually carries the URI where the invoice can be retrieved, so this Peppol BIS 3.0 Greek country rule requires the URI to accompany the reference.

Official rule text

When Supplier is Greek and the INVOICE URL Document reference exists, the External Reference URI should be present

Common causes

• AdditionalDocumentReference described as the invoice URL but cac:Attachment/cac:ExternalReference/cbc:URI omitted
• Empty URI element inside the external reference

How do I fix it?

<cac:AdditionalDocumentReference>
  <cbc:ID>INV-2026-001</cbc:ID>
  <cbc:DocumentDescription>INVOICE URL</cbc:DocumentDescription>
  <cac:Attachment>
    <cac:ExternalReference>
      <cbc:URI>https://invoices.example.gr/INV-2026-001</cbc:URI>
    </cac:ExternalReference>
  </cac:Attachment>
</cac:AdditionalDocumentReference>
