FX-SCH-A-000447: Use an allowed seller electronic address scheme

In short

Error: fails the selected checks.

FX-SCH-A-000447 means a non-empty scheme code for your seller's electronic address (BT-34-1) is not in the Basic WL profile's list. Use the listed scheme matching the address, such as EM for email or 0088 for a GLN.

What it means

In the Factur-X and ZUGFeRD Basic WL profiles, this rule checks schemeID on ram:SellerTradeParty/ram:URIUniversalCommunication/ram:URIID against the profile's electronic address scheme list. An empty code value passes this test; FX-SCH-A-000446 separately requires the attribute to exist.

Why it matters

The scheme code gives the seller's electronic address a defined type within the profile. Code list membership does not establish whether delivery is possible.

How to fix it

Correct schemeID on the seller's ram:URIID to match the address you supplied. For email, use EM rather than EMAIL or MAIL. For another address type, use its matching listed scheme. Export your corrected file and recheck it.
