fatalPeppol BIS Billing 3.0profileCIIUBL
Business process MUST be provided.
The business process identifier (BT-23) is missing. Peppol routes on it, so an invoice without it cannot be delivered even though it is valid EN 16931.
Add BT-23 (UBL cbc:ProfileID) with the value urn:fdc:peppol.eu:2017:poacc:billing:01:1.0 for a normal invoice-only process. This is the field most often missing when a working EN 16931 file first meets Peppol.
