Did Not Work
Your timecard might feature a 'Did Not Work' toggle. Using this functionality is required because empty timecard entries indicate that you might have worked during a day or time period, but have not submitted time for that day or week or time period.
The 'Did Not Work' functionality must be supported for a timecard (Hourly 1, Hourly 4, and so on) and added to a work period defined for client organizations. You can only configure either a daily setting, or an entire work period. See Work Periods and Calendars.
