FX-SCH-A-000424: Use an allowed buyer registration scheme

In short

Error: fails the selected checks.

FX-SCH-A-000424 means the non-empty scheme code (BT-47-1) for your buyer's company registration number (BT-47) is not allowed by the Basic WL profile. Correct schemeID on ram:BuyerTradeParty/ram:SpecifiedLegalOrganization/ram:ID to a listed code for the actual register.

What it means

This Basic WL rule for Factur-X and ZUGFeRD compares a non-empty registration scheme with the profile's permitted codes. A missing or empty schemeID does not fail this test.

Why it matters

The scheme identifies the register or numbering system associated with the buyer's company registration number.

How to fix it

Check which register issued the number and use its code from the Basic WL list, for example 0106 for a Dutch KvK number or 0009 for a French SIRET. Correct ram:BuyerTradeParty/ram:SpecifiedLegalOrganization/ram:ID/@schemeID. If your invoice does not require a scheme, omit that attribute rather than guessing, and keep the registration number. Export and recheck your file.
