What it means
In the Extended profiles of Factur-X and ZUGFeRD, qdt:DateTimeString under ram:SellerOrderReferencedDocument/ram:FormattedIssueDateTime in the header trade agreement must have a format attribute. This test checks only attribute presence. It does not require the specific code 102, reject an empty attribute or check the date text. FX-SCH-A-000756 checks non-empty format codes against the allowed list.
Why it matters
The format attribute records how the seller's order date is written. The profile requires that attribute on this date element.
How to fix it
Correct the seller's order reference date in your invoice data or export mapping. In XML, add format to qdt:DateTimeString under ram:SellerOrderReferencedDocument/ram:FormattedIssueDateTime. Choose a code from the profile's allowed date format list and make sure the date text follows that format. Recheck the corrected file.
