This can be very easily for any given day.
- Go to the Timesheets menu in LMN Time
- Click the Payroll Warnings tab on the left side
- Choose the date you want to view (you can even view the current day live as-it's-happening!)
The payroll warnings screen will display a list of employees (active only) who are not accounted for on a timesheet dated for that day.
Note: during snow season when employees may be working over a midnight/2-day shift, you may need to check both dates depending on the date the timesheet was created.
