This server event is available in version 2017.1 and later.
The OnScheduledReportComplete server event occurs when a scheduled report execution completes, regardless of whether it was successful or not. It precedes creation of the output file. The schedule job object is passed in the args array so the job can be examined for potential errors.
For custom code the args array is structured as follows:
args contains one argument, a SchedulerJob object representing the completed scheduled execution.
For .Net Assemblies the method signature is as follows:
string EventHandlerName(SessionInfo sessionInfo, SchedulerJob job)
The OnScheduledReportComplete server event expects a boolean return value to indicate whether to create the report output for the job.
