FX-SCH-A-000930: The payer may have only one electronic address

In short

Error: fails the selected checks.

FX-SCH-A-000930 means the payer has more than one electronic address block (ram:URIUniversalCommunication). Keep one and remove the others.

What it means

The payer (ram:PayerTradeParty), the party that pays the invoice when that is not the buyer, may have one electronic address, such as an email address or a Peppol ID (ram:URIUniversalCommunication). The rule fails when there are two or more such blocks.

Why it matters

The Extended profile allows a single electronic address for the payer. Extra blocks do not fit the structure, so the file fails the check and the recipient can reject it.

How to fix it

In your invoicing software, check the payer's details and keep one electronic address. If you need to give more than one way to reach the payer, use the contact details instead. In the XML, ram:PayerTradeParty may contain one ram:URIUniversalCommunication.
