What it means
The Extended profiles of Factur-X and ZUGFeRD check a non-empty format attribute on qdt:DateTimeString under ram:SellerOrderReferencedDocument/ram:FormattedIssueDateTime against code list 17. An empty value is not rejected by this test. FX-SCH-A-000755 separately checks attribute presence. Neither test checks the date text itself.
Why it matters
The format code identifies the notation used for the date. It must come from the profile's permitted list, while the date text needs to match the selected notation.
How to fix it
Find the seller's order reference date in your invoice data or export mapping. Correct format on qdt:DateTimeString under ram:SellerOrderReferencedDocument/ram:FormattedIssueDateTime to a permitted date format code. Check that the date text uses the corresponding notation. Regenerate the file if needed and recheck it.
