What master data warnings mean

Nordflow checks supplier master data on every incoming invoice and raises a visible warning when something has changed in a way that warrants a second look. The check happens automatically; you don’t need to do anything to trigger it.

Two main warning types

New supplier. The supplier on the invoice does not yet exist in your ERP as a creditor. The warning signals that someone should decide whether to create this supplier in master data before the invoice is posted.

Payment information changed. The supplier’s bank account number, registration number, or payment method on the current invoice differs from what was on the previous invoice from the same supplier. This is the most important warning. Legitimate payment-detail changes do happen, but this is also the pattern used in accounts-payable fraud: a realistic-looking invoice arrives with a slightly different bank account. The warning is the system telling you to verify before you approve.

Administrators can also configure additional checks, such as duplicate invoice detection or unusual amounts.

Warnings are not blocks

A warning does not stop you from approving. It is a deliberate checkpoint. If you approve through a warning, that fact — including what specifically changed — is recorded in the document’s activity history, so the decision is visible in the audit trail.
