Query Builder - determine who is running reports

using bi platform 4.1 is there a way via query builder to find what users have been running which crystal report? not just scheduling them but running them via the bi launchpad?

totals would be best but even something similar to what is below would work but i would also need the name of the report

SELECT SI_ID, SI_NAME, SI_RECENT_DOCUMENTS, SI_RECEIVED_ALERTNOTIFICATIONS

FROM CI_SYSTEMOBJECTS WHERE SI_KIND='USER'

thanks for any help.
