SSRS-Types of Reports

In Reporting Services, you can use reports in a variety of ways. This topic describes the terminology used to describe the various types of reports and the ways reports get created and used. A single report can have characteristics from more than one type; for example, snapshot reports can be parameterized, ad hoc reports incorporate clickthrough report functionality due to the report models upon which they are based, and subreports can be linked reports.
With Reporting Services, you can create the following types of reports:
Parameterized reports
Linked reports
Snapshot reports
Cached reports
Ad hoc reports
Clickthrough reports
Drilldown reports
Drillthrough reports
Subreports
