FX-SCH-A-000772: Add a scheme to the tax representative's electronic address

In short

Error: fails the selected checks.

FX-SCH-A-000772 means schemeID is missing from the seller's tax representative's electronic address element, ram:URIID. Add the attribute with the code matching the address type, such as EM for email.

On this page

What it means

For each ram:URIID inside ram:SellerTaxRepresentativeTradeParty/ram:URIUniversalCommunication, this rule checks that schemeID exists. It does not check whether the attribute is empty or whether its code is allowed. FX-SCH-A-000773 separately checks non-empty scheme values.

Why it matters

The scheme identifies the type of electronic address. The Extended profiles of Factur-X and ZUGFeRD require the attribute on this element.

How to fix it

Add schemeID to the tax representative's ram:URIID and set it to the code for the address type, such as EM for email. If you omit the electronic address entirely, remove the whole ram:URIUniversalCommunication block so you do not leave it without the ram:URIID required by FX-SCH-A-000771. Export the file again and recheck it.
