Limit on number of days selected

The user is able to display any date range to view employee schedules in the Shift History screen. However, an upper limit is established in the system to prevent performance issues or degradation in system response. This configurable limit restricts viewing to a maximum number of weeks in the Shift History screen.

The limit is configurable using the /system/modules/emvs/SH_MAX_DAYS_FOR_DATE_RANGE registry parameter.

The default value of this parameter is 63 days. Be cautious when modifying this parameter. Use a reasonable date range because shift history also retrieves information regarding an employee’s past schedules. These past schedules can contain large amounts of information, which can stress the system. This stress can cause performance issues.
