FX-SCH-A-001094: Line delivery contact fax needs one number element

In short

Error: fails the selected checks.

FX-SCH-A-001094 means a fax block for the delivery contact on an invoice line contains no ram:CompleteNumber element or contains more than one. Include one ram:CompleteNumber with the intended fax number, or remove the block if you have no fax number to report.

What it means

Each ram:FaxUniversalCommunication inside the line delivery party's ram:DefinedTradeContact must contain one ram:CompleteNumber child. This rule counts elements; it does not check whether the number text is present or valid.

Why it matters

The Extended profile represents each contact fax block with a single number element.

How to fix it

Check the fax details of the line's delivery contact. In XML, use one ram:CompleteNumber inside ram:SpecifiedLineTradeDelivery/ram:ShipToTradeParty/ram:DefinedTradeContact/ram:FaxUniversalCommunication. Put the intended fax number in that element and remove additional ram:CompleteNumber elements. If you have no fax number to report, remove the fax block. Export and recheck your file.
