What it means
The format attribute on qdt:DateTimeString under ram:SpecifiedLineTradeDelivery/ram:DeliveryNoteReferencedDocument/ram:FormattedIssueDateTime is checked against code list 17 in FACTUR-X_EXTENDED_codedb.xml. An empty value passes this rule. A missing attribute is checked separately by FX-SCH-A-001079.
Why it matters
The format code identifies how the delivery note date text is written. The profile restricts which codes you can use.
How to fix it
Correct format on the affected delivery note's qdt:DateTimeString. For a date written as YYYYMMDD, use format="102"; if you use another allowed format, keep its code and date text consistent. Export the corrected file and check it again.
