Greek invoice is missing its invoice URL
What it means
Greek e-invoicing expects a reference URL where the invoice can be retrieved, tying the Peppol document back to the copy registered domestically.
Can it be fixed automatically?
The fix is mechanical once you provide the value, but the value itself is yours: it cannot be derived from the invoice and will not be guessed.
How to fix it
Supply the URL under which this invoice is published. It is generated by your own system and cannot be derived from the invoice content.
Where it applies
