FX-SCH-A-000945: Identify the payer's tax registration scheme

In short

Error: fails the selected checks.

FX-SCH-A-000945 means a ram:ID for the payer's tax registration is missing its schemeID attribute. Add the attribute using the scheme code that identifies the type of number you have supplied.

What it means

The ram:ID in ram:PayerTradeParty/ram:SpecifiedTaxRegistration must have a schemeID attribute. This rule checks only that the attribute exists. An empty attribute also passes this presence test.

Why it matters

The scheme identifies what kind of tax registration number the payer has supplied.

How to fix it

On ram:PayerTradeParty/ram:SpecifiedTaxRegistration/ram:ID, add schemeID with the appropriate scheme code, such as VA for a VAT number. Check any separate restrictions on scheme values in your profile. Export the corrected file and recheck it.
