Escalation from approver to manager using organizational plan.

Hi all,

I have to escalate the the User decision step to the manager if the approver does not respond to the users request in 3 days. The employee, approver and manager Hierarchy is maintained in the oraganizational plan.

I am able to esacalate to the approver based on the employee based rule '168'.

Now how to escalate it to manager if the approver has not responded in 3 days.

Regards,
