What it means
For each ram:SpecifiedLineTradeSettlement on an invoice line, the test counts direct ram:InvoiceReferencedDocument children. It allows none or one and does not check the referenced invoice's date or details.
Why it matters
This line-level reference has a maximum of one entry per settlement block. The limit applies both to repeated references to the same invoice and to references to different invoices.
How to fix it
Compare the references in the affected line settlement with your invoice records. Keep the appropriate ram:InvoiceReferencedDocument, if needed, and remove extra entries. If several references are genuinely needed, ask your software supplier how to represent them within your chosen profile. Export the file again and recheck it.
