Summary:
The number of Time Off hours allowed to be entered on the timesheet is controlled by the Hours Per Day set on a user's profile. If the user's Hours Per Day is set to 8 then the user can add only 8 hours to the time off type selected on the timesheet. 
Users will see an error: Hours per day must be less than or equal to <default hours per day> when they attempt to save or submit a timesheet with time off hours that exceeds the Hours Per Day set for that user.
