For example, you can create a requisition such that if the total is less than $500, the requisition is routed to the purchasing department. If the requisition total exceeds $500, the requisition requires the approval of the department manager before it can be routed to the purchasing department. If the requisition total exceeds $1,000, the requisition requires the approval of a vice president before it can be routed to the purchasing department. If the requisition total exceeds $5,000, the requisition requires the approval of the chief financial officer before it can be routed to the purchasing department.
