Insight supports dashboards that are "forward-looking" and have the date range locked to no earlier than the current month and no later than one year ahead. The Upcoming and Forecast preset dashboards are the only presets that have this constraint, while all other preset dashboards lack date range limits.
Insight manages separate date ranges for each of these two types of dashboards, and you can select the default date range for each type in the Settings page -> Date & Time tab. The default date ranges are the ranges that first load into the date picker when the application is started (or when you perform a browser reload). Therefore, saving a new date range will not immediately change the date range that you are currently using as a global filter setting on the application. If you wish to change the date range immediately, please change the date range in the date picker.
Suppose you reload the application and first visit a forward-looking dashboard. The date range will be set to the default date range for forward-looking dashboards. Let’s assume this is “Next 7 days.” If you change the date range in the date picker to “Current month” and then navigate to a dashboard without date range limits (such as Reservations), the date range will change to the default date range for dashboards without date range limits. Suppose this is “Past 28 days.” If you change the date range in the date picker to “Past 7 days” and navigate to another dashboard without date range limits (such as Cancellations), the date range will remain “Past 7 days” until you click on any forward-looking dashboard. Once you click on a forward-looking dashboard, the date range will automatically change to “Current month,” which was the most recently selected date range for forward-looking dashboards (not the default in user settings).
