What it means
The check compares a non-empty format attribute on ram:BuyerOrderReferencedDocument/ram:FormattedIssueDateTime/qdt:DateTimeString with the profile's date format list. An empty value passes this test. FX-SCH-A-000670 separately checks whether the attribute exists.
Why it matters
An accepted format code describes a date representation defined by the profile.
How to fix it
Check the date text in the purchase order's qdt:DateTimeString and replace its format attribute with the matching accepted code. For an eight-digit date in year, month and day order, use 102. Do not put a pattern such as YYYYMMDD in the attribute. Export the invoice again and recheck it.
