How to trigger approval WF for manually added Freight line to buyer of the PO at Invoice header?

Hi Everyone,

We have a requirement to setup approval workflow for the below use case:

The supplier is creating a PO-matched invoice from the supplier portal, on this invoice supplier is adding a non-PO-matched freight line. Now because there is this non-PO matched freight line it is required to trigger a workflow to the buyer of the PO on another line. Any thoughts on how I can configure approval rules to achieve this?

Thanks in advance.

Regards,
