In addition to the scope selector, additional filtering can be achieved via the Dynamic Template Designer. This filter is a static filter—that is, unlike the filter in the Report Scope Selector, this filter cannot be changed at report run time. See also, Static Filter vs. Tabular Report Filter

Filters can be defined in the Dynamic Template Designer and also in the report scope selector. At run time, the system uses the filter that is the most restrictive. For example, if you defined a date filter of the Last 12 Hours, but your scope selector is configured for Last 4 Hours, the report results will display the events for the Last 4 Hours.

Click Add to configure the Field, Operation, and Value of a filter. See Filter on Date Fields.
