What we want is the timesheets to go first to the person that is already setup as approver and then he to delegate the timesheet approval to another employee. Can I do this at timesheet entry using vacation rules?
Vacation rules transfer all the notifications from the person to the one who it is delegated. Once you set up the vacation rule all the notifications for this person will go to the person who will be delegated. Try this.
Can I delegate to more than one person depending of the employee name or employee cost center?
Depending of the cost center/organisation assigned to the employee the timesheet needs to be delegated to a different approver.
Is there any other way to satisfy this requirement? Only vacation rules are available?
