Projects workflow optional routing to PM

Summary:

Content (required):

We have varying requirements for workflow approval of project-related AP invoices and expense reports. Some business areas want these project transactions routed to the Project Manager for workflow approval, while others only want the employee supervisor or cost centre manager approval without any PM approval.

Is there a standard approach to flag an individual project as requiring or not requiring PM approval on an AP invoice, expense report or procurement requisition?

Alternatively, can PM approval be determined by each Business Unit?

Thanks,

Brian
