What it means
The check requires a format attribute on ram:BuyerOrderReferencedDocument/ram:FormattedIssueDateTime/qdt:DateTimeString. It checks only whether the attribute exists. FX-SCH-A-000671 separately checks non-empty format codes against the accepted list.
Why it matters
The format attribute labels the representation used for the purchase order date.
How to fix it
Add format to qdt:DateTimeString inside ram:BuyerOrderReferencedDocument/ram:FormattedIssueDateTime. If the date uses eight digits in year, month and day order, set format to 102. Keep the code and date text consistent, then export the invoice again and recheck it.
