What it means
The rule checks format on qdt:DateTimeString under the line's ram:SpecifiedLineTradeSettlement/ram:InvoiceReferencedDocument/ram:FormattedIssueDateTime against code list 17. An empty or missing value passes this code-list test. FX-SCH-A-001134 separately requires the attribute to exist.
Why it matters
The format code tells software how to interpret the referenced invoice's date text.
How to fix it
Correct format on the affected qdt:DateTimeString and ensure that the date text matches it. For format="102", use eight digits as YYYYMMDD, including leading zeros for the month and day. If your software writes an unsupported code, ask its supplier to correct the export. Export again and recheck.
