LOA: How to restrict the levels of approvers from Hr Hierarchy

Hi all,

We are in process of implementing Time and Labor module in HR Self Service R12 (12.1.3).

We want the WF to end at the first level approver. For example if an employee "A" submits his Leave of Absence would go to his supervisor "B" and once "B" approves the WF should complete and not continue to "B" supervisor "C".

Is there any setup which could be done through AME to complete after first level? Please advise, if yes how to do or is there any document that I could refer back.

Thanks,

BKN
