We are using timesheet management in PPM and needs two levels of time approvers to approve the timesheets. At the first level the timesheet should get approved by the resource managers and once approved, it should be approved by senior manager.
However, I can see that only one time approver manager can be selected for any resource. Also, our scenario is separate than the option for "Billing Approver". The timesheet itself needs to be approved by two managers.
We also have the requirement that the Senior manager should be able to view the timesheet only once it is approved by resource manager.
Similarly as for the other thread you created, as far as I can tell this scenario of time approval is an Enhancement Request.
