Mandate reference MUST be provided for direct debit.

Why it fails

A direct debit is used without a mandate reference.

How to fix it

Add the mandate reference (BT-89) in PaymentMandate/cbc:ID. Without the mandate the buyer's bank has no authority to let you collect.

This is a Peppol BIS Billing 3.0 rule: an invoice can be perfectly valid EN 16931 and still be rejected by it.
