If you want to change an approver on a requisition after the requisition has already been submitted for approval, merely changing the approver by using the Edit feature will not work. You need to cancel and re-open the requisition first. Here is how to change approvers:

• Go to the Manage Requisitions page.
• Click on the Edit Requisition icon.
• Inside the requisition, click on the Settings link and change the approver.
• Click the Submit button on the requisition on the Requisition Summary page.
