FX-SCH-A-000990: Payee contact fax needs one number element

In short

Error: fails the selected checks.

FX-SCH-A-000990 means a fax block for the payee's contact in your payment terms has no ram:CompleteNumber element or more than one. Put the fax number in one ram:CompleteNumber, or omit the fax block if you are not providing a number.

What it means

Each ram:FaxUniversalCommunication under ram:SpecifiedTradePaymentTerms/ram:PayeeTradeParty/ram:DefinedTradeContact must contain one ram:CompleteNumber element. This rule counts elements; it does not check whether the number is filled in or valid.

Why it matters

ram:CompleteNumber is where the fax block holds its full number, and the block requires one such element.

How to fix it

Check the payee contact's fax block under ram:SpecifiedTradePaymentTerms/ram:PayeeTradeParty/ram:DefinedTradeContact. Keep one ram:CompleteNumber containing the correct fax number inside ram:FaxUniversalCommunication. If you are not providing a fax number, omit that block. Export the corrected file and check it again.
