We have a need to have an approval from accounting take place whenever certain tax codes/states are selected. In addition, we don't want the customer to be used/process further until the approval has taken place. Would this be best done through the BC approval, and if so what is needed, or through Power Automate? It appears that despite sending a customer approval, the customer can still have orders/invoices entered, is that correct? What good is the customer approval for?
