ITA Reports are not like DLP Reports.
DLP Reports are run directly against the DLP database, drawing from the data available in the DLP database at the time the report is run.
ITA Reports do not reference the direct data when run, they use cached data collected from DLP when the OLAP Cube is processed in the SQL Analysis Server.
As such, there is no 'schedule' that a report is run. When you open a report in ITA, it is SQL Reporting Services looking at the OLAP Cube data from SQL Analysis Server. That data may be 5 minutes or 5 days old - depending upon when the cube (and its measures) were last processed.
Delivering reports via email to users can be handled using Subscriptions in the Reporting Services instance - (see SQL Reporting Services). You can also leverage the Reporting Services instance to publish these reports to other locations within your environment e.g. SharePoint, Intranet etc.
