Explanation
A seller based in Greece reports each invoice to myDATA, the Greek tax authority's reporting system, and receives a unique registration number for it, the MARK. PEPPOL requires the invoice to contain exactly one reference with this number, as a document reference described as ##M.AR.K##.
How to fix
Ask the seller for a corrected invoice with exactly one reference to the MARK number myDATA assigned to this invoice.
