Error

FX-SCH-A-001131: The tax type code on a line must be a valid code

In short

Error: fails the selected checks.

FX-SCH-A-001131 means a non-empty tax type code in an invoice line's ram:ApplicableTradeTax is not allowed. Correct ram:TypeCode using the permitted code for the tax being reported; for VAT, use VAT in capitals.

What it means

The rule checks ram:TypeCode under the line's ram:SpecifiedLineTradeSettlement/ram:ApplicableTradeTax against code list 26. An empty value passes. This is a code-list check, not an unconditional test that the value equals VAT.

Why it matters

The tax type identifies which tax the accompanying category, rate and other details describe.

How to fix it

Check the tax reported in the affected ram:ApplicableTradeTax and correct its ram:TypeCode. If it is VAT, use VAT rather than a local name such as MwSt, TVA or BTW. Do not change the intended tax type merely to clear the error. Export again and recheck.
