FX-SCH-A-001074: Add the line delivery date format attribute

In short

Error: fails the selected checks.

FX-SCH-A-001074 means a line's delivery date is missing its format attribute. Add the attribute to udt:DateTimeString inside the delivery event's ram:OccurrenceDateTime, using a code that matches how you write the date.

What it means

The udt:DateTimeString under ram:SpecifiedLineTradeDelivery/ram:ActualDeliverySupplyChainEvent/ram:OccurrenceDateTime must have a format attribute. This rule checks that the attribute exists, not whether its value or the date text is valid.

Why it matters

The format attribute identifies how the line's delivery date text is written.

How to fix it

Check the XML exported for the affected line's delivery date. Add format to udt:DateTimeString inside ram:ActualDeliverySupplyChainEvent/ram:OccurrenceDateTime. For a date written as YYYYMMDD, use format="102". Keep the date text consistent with the chosen code, then check the corrected file again.
