Financial Approval being bypassed for requisition where PM on project is no longer active

Summary:

Financial Approval being bypassed for requisition where PM on project is no longer active. Project Manager Approval is bypassed when PM is made an inactive employee

Content (please ensure you mask any confidential information):

A requisition has been raised through a PM routed project where the PM is no longer in the business.

Approval showed as errored in the Transaction Control screens, however approval still showed for the Buyer and Procurement Financial Approval Groups. And once approved, showed as a completed state.

Can a new rule be added (to the ReqApproval workflow) to reject requisitions with an inactive PM?
