FX-SCH-A-001104: Tax registration of the delivery party needs a scheme

In short

Error: fails the selected checks.

FX-SCH-A-001104 means the tax registration number of the delivery party on an invoice line has no scheme. Add the code that says what kind of number it is, usually VA for a VAT number or FC for a tax number, or remove the number.

What it means

The tax registration (ram:ID inside ram:SpecifiedTaxRegistration) of the delivery party on an invoice line must say what kind of number it is, in the attribute schemeID. In practice VA stands for a VAT number and FC for a national tax number. This rule only checks that schemeID is there, not what it says.

Why it matters

A tax number without a type is ambiguous. The recipient cannot tell whether it is a VAT number or a national tax number, so the file fails the structure check of the Extended profile and is reported as invalid.

How to fix it

In your invoicing software, open the delivery party of the line and check how its tax number is entered. Choose whether it is a VAT number or a tax number, so the software writes the scheme with it. If you do not need the number, clear it. In XML, add schemeID with a value such as VA to the ram:ID inside ram:SpecifiedTaxRegistration.
