What does GR-R-005 mean? Greek Suppliers must provide the full name of the buyer

Why did my invoice fail GR-R-005?

Greek suppliers must provide the full name of the buyer on the invoice. This Peppol BIS 3.0 Greek country rule ensures the customer party is fully identified; in UBL the buyer name is carried in cac:AccountingCustomerParty/cac:Party/cac:PartyLegalEntity/cbc:RegistrationName.
