GR-R-001-3
What does GR-R-001-3 mean? When the Supplier is Greek, the Invoice Id second segment must be a valid Date that matches the invoice Issue Date
Why did my invoice fail GR-R-001-3?
For Greek suppliers, the second segment of the Invoice number must be a valid date and must equal the invoice's Issue date (BT-2, cbc:IssueDate). Embedding the issue date in the identifier lets the Greek tax infrastructure verify the invoice ID is consistent with the document itself.
Official rule text
When the Supplier is Greek, the Invoice Id second segment must be a valid Date that matches the invoice Issue Date
Common causes
- Date segment formatted differently or not a real date
- Invoice ID generated before the issue date was finalised, so the two disagree
- Issue date changed on reissue without regenerating the invoice ID
