FX-SCH-A-000703: Use an allowed scheme for the buyer's tax registration

In short

Error: fails the selected checks.

FX-SCH-A-000703 means a scheme code on your buyer's tax registration is not allowed by the Extended profile. Correct schemeID to match the type of tax number.

On this page

What it means

A non-empty schemeID on ram:ID inside the buyer's ram:SpecifiedTaxRegistration must match the profile's tax registration scheme list. An absent or empty attribute does not fail this value check.

Why it matters

The scheme identifies the type of tax registration, such as a VAT number or a national tax number.

How to fix it

Check the buyer's VAT number (BT-48) and any national tax number. In your CII XML, correct schemeID on ram:BuyerTradeParty/ram:SpecifiedTaxRegistration/ram:ID. Use VA for a VAT number. Export the corrected file and recheck it.
