You can disable selection-based interactivity for an HTML report that is viewed in Cognos Viewer to shorten the time that it takes the report to run. After you disable this functionality, you cannot:
drill up and down in a report
drill through to other reports
use Cognos Search
use conditional report delivery
use agent notification
If selection-based interactivity is enabled in Cognos Connection, a user can perform drill up and down and drill-through actions in Report Viewer or Query Studio. If selection-based interactivity is disabled in Cognos Connection, the ability to perform drill up and down and drill-through are disabled regardless of how the drill through definitions and settings are authored in Report Studio and Cognos Connection.
Selection-based interactivity is enabled by default.
Tip: You can instead enable or disable selection-based interactivity for the current run only.
Click Run with options next to the report and then click Advanced options. Click Enable selection-based interactivity in HTML reports.
In Cognos Connection, click the set properties button 
on the actions toolbar to the right of the
report.
Click the Report tab for a Report Studio report, the Query tab for a Query Studio report, or the Analysis tab for an Analysis Studio report.
Tip: Disabling selection-based interactivity on an Analysis Studio report has no effect.
Click Advanced options.
Clear the Enable selection-based interactivity in HTML reports check box.
Note that disabling selection-based interactivity on an Analysis Studio report has not effect.
