I just created a new report in Explore. Why does the Ticket Created - Date filter automatically apply to my report?
The Ticket Created - Date filter is applied to new reports in Explore to improve the loading of data in the visualization tool.
When you start a report without setting a time filter, the calculations begin to review the entire history of your account data. This can cause performance issues and slowness in Explore. Adding the Ticket Created - Date filter narrows the time frame of data and returns faster results.
If your report does not require a time filter, it can be adjusted or removed.
