Timesheets need to be submitted even though the time off bookings were submitted for the entire timesheet period since,

  • Timesheet and Time Off are separate functions in Web TimeSheet.
  • Time and Time Offs are tracked separately.
  • Timesheet and Time Off have distinct approval paths.

Note:
The time off bookings are populated on a user's timesheet representing that the user haven't recorded time against any tasks/activities but was on off during that period.
