FX-SCH-A-001066: The tax type of a tax included in the price must be allowed

In short

Error: fails the selected checks.

FX-SCH-A-001066 means the tax type code of a tax included in the net unit price of a line is not an allowed code. For VAT, use the code VAT.

On this page

What it means

The tax type code (ram:TypeCode) of a tax included in the net unit price of a line must be one of the codes in the code list of the Extended profile (code list 23 in its code database). For VAT the code is VAT. An empty value is not tested by this rule.

Why it matters

The tax type tells the recipient which tax the amount belongs to. A code outside the agreed list cannot be interpreted, so the file fails the check and the recipient may reject it.

How to fix it

In your invoicing software, check the tax type set for the item on the line. It should be VAT unless you really include a different tax in the price. If you build the XML yourself, correct ram:TypeCode inside ram:IncludedTradeTax under ram:NetPriceProductTradePrice.
