Factur-X
Element 'ram:IssuerAssignedID' must occur exactly 1 times.
Mandatory rule: As long as it is violated, the invoice is invalid and will be rejected by validators.
What is wrong
ram:IssuerAssignedID is missing from ram:InvoiceSpecifiedReferencedDocument or occurs more than once. It must occur exactly once.
What the rule means
The issuer-assigned ID identifies the referenced document. Without exactly one such value, the advance payment cannot be unambiguously linked to that document.
Please provide the issuer ID of the referenced document exactly once
The referenced document for the advance payment is missing its issuer ID, or the ID appears more than once. Providing it exactly once makes the reference unambiguous.
What to do
- Find the advance payment’s
ram:InvoiceSpecifiedReferencedDocument. - Make sure it contains exactly one
ram:IssuerAssignedID. - Generate the invoice again and validate it once more.
