FX-SCH-A-001089: Line delivery party may have only one identifier

In short

Error: fails the selected checks.

FX-SCH-A-001089 means the delivery party on an invoice line has more than one ram:ID element. Remove the extra elements, keeping the correct identifier if you need to report one, then export and recheck.

What it means

This rule permits zero or one direct ram:ID child inside each ram:ShipToTradeParty under ram:SpecifiedLineTradeDelivery. It counts elements, even if their values are identical. It does not count ram:GlobalID.

Why it matters

The Extended profile provides a single identifier field at this location rather than a list of identifiers.

How to fix it

Check the identifier for the line's delivery party in your invoice data. In XML, retain at most one ram:ID directly inside ram:SpecifiedLineTradeDelivery/ram:ShipToTradeParty. Remove repeated ram:ID elements. A ram:GlobalID is a separate field and is not part of this count. Export and recheck your file.
