Error

FX-SCH-A-000696: The buyer's contact fax entry needs one number element

In short

Error: fails the selected checks.

FX-SCH-A-000696 means a fax entry for your buyer's contact contains no ram:CompleteNumber element or more than one. Correct that fax entry so that it contains one number element.

On this page

What it means

For each ram:FaxUniversalCommunication inside ram:BuyerTradeParty/ram:DefinedTradeContact, this rule requires one ram:CompleteNumber child element. An empty ram:CompleteNumber still counts as one element; this rule does not check its contents.

Why it matters

The Extended profile gives each fax entry one place for the complete number. Multiple number elements exceed that limit even if their values are identical.

How to fix it

Check ram:BuyerTradeParty/ram:DefinedTradeContact/ram:FaxUniversalCommunication in the header trade agreement. Add a missing ram:CompleteNumber with the contact's fax number, or keep the correct element and remove duplicates. Do not treat adding an empty element as completing the contact details. Recheck your corrected file.
