How to Route Invoice Approval Based on Requestor Department in Requestor Assignment Details > Depart

Summary

We have only 1 business unit and we set-up users listing their home department in the manage users section. I'd like to be able to drive the invoice routing by the requestors department set-up

I'm trying to see if there is a way to drive an invoice routing based on the requestor's set-up in the Manage Users > Assignment Details > Department area.

We have only 1 business unit and we assign users to home departments within the organization. There is a requirement to have different approval rules based on the requestor's home department. I know I can drive the rule based on the Cost Center Segment on the invoice line but there are instances in which the invoice can be coded to multiple departments. In this case the requirement is still to use the requestors home department to drive the invoice workflow.
