Go to Settings > Human Resource Settings
Select the Request Approval tab.
On each type of request, select the employee positions that are allowed to approve the requests.
<aside> 💡 The order of the Approver is important since the last approver has the final decision. If all approvers are filled-in, Approval 3 has the final decision. If Approval 3 is empty then Approver 2 has the final decision. If Approval 2 and 3 are empty then the final decision is Approver 1.

Note: On the request forms, these 3 approvers will show including the selected Supervisor who will Pre-approve the request.
