What it means
When the seller country value is GR or EL, each existing seller cbc:EndpointID must have schemeID equal to 9933 and a value that passes the Greek TIN check. The XPath does not separately check whether the document is being sent through Peppol, and it does not detect a missing cbc:EndpointID.
Why it matters
Scheme 9933 tells software to interpret the electronic address as a Greek TIN. The scheme and the address value need to describe the same identifier. This check does not establish recipient rejection.
How to fix it
Confirm your company's Greek TIN against your tax details. Put its nine digits, without EL, in cac:AccountingSupplierParty/cac:Party/cbc:EndpointID and set that element's schemeID attribute to 9933. Keep the scheme separate from the element's text. Check the corrected file again.
