BR-FR-23_EXT-FR-FE-121: Seller's service provider electronic address must use only allowed characters

In short

Fatal: fails the selected checks.

BR-FR-23_EXT-FR-FE-121 means the electronic address of the seller's service provider in UBL or the invoicer in CII (EXT-FR-FE-121), using scheme 0225, contains an unsupported character. Confirm the correct address and enter it using only letters A to Z and a to z, digits, plus signs, hyphens, underscores and full stops.

What it means

In UBL invoices and credit notes, this rule checks cac:AccountingSupplierParty/cac:Party/cac:ServiceProviderParty/cac:Party/cbc:EndpointID only when schemeID is 0225. In CII, it checks ram:InvoicerTradeParty/ram:URIUniversalCommunication/ram:URIID only when schemeID is 0225. The electronic address may contain only letters A to Z and a to z, digits, plus signs (+), hyphens (-), underscores (_) and full stops (.).

Why it matters

The French rules restrict the characters you can use in this service provider's electronic address with scheme 0225. A value outside that set fails this check.

How to fix it

Find the electronic address of the seller's service provider in UBL or the invoicer in CII (EXT-FR-FE-121). Confirm the address and its scheme with that provider or invoicer, then correct the value or schemeID of cbc:EndpointID in UBL or ram:URIID in CII if either was recorded incorrectly. Do not simply strip characters from an address without verifying it. Export the corrected file and check it again.
