Triggering a schedule by event, not time

[jasonnm]

Hi there,
I have created a schedule to run my report every x minutes/hours/days/etc. and it's working perfectly.
But is there a way to trigger the report to be run on an event instead? For example, I have a stored procedure to aggregate a large amount of data, and persist the results in MongoDB for faster retrieval.
How would I trigger my report to run only when the data is "ready". Depending on many factors, the data would not always be available at the same time each day.

Thanks,
J

Can't you trigger the normal API call from within your app/client?
