Hi Rajesh,
Ideally, you can use the Packages Schedule Status in BPC Excel to cancel the scheduled jobs.
If that is not an option, you can clear the scheduled jobs from the dbo.tblSchedule table in the appset database. BPC uses Windows Task Scheduler to run scheduled packages, so if you manually clear the jobs from the table, you will also need to remove the tasks from Windows Task Scheduler on the scheduler server (usually the application server).
Thanks,
Scott
