The Process Watcher is a monitoring facility for manually executed schedules. You can enable this in Options (Tools > Options) on the General tab in the User Experience section.
The Process Watcher enables you to execute multiple reports and watch them execute.
The schedules will then go through the stages of execution...
Any schedule can then be cancelled from the Process Watcher at any stage of execution. Right click on the schedule and select Cancel Execution.
You will be asked to confirm the cancellation.
The schedules may be at different stages of execution.
You could still at this stage cancel any of the remaining reports following the same process.
Disable the Process Watcher
You can disable the process watcher if desired.
Go to the options menu, under general. Uncheck "use Process Watcher." SQL-RD will no longer display the process watcher when the schedule is manually executed. You can still review an active schedules status in the System Monitor.
