I have recently had a dataset which is sent out daily with a reporter. Recently I had a day where the dataset built fine and however it wasn't sent out properly and through a warning in the reporter section. I just had to run the job manually again and it went fine.
What I want to know is if it is possibly to trigger a scenario using the warning thrown from the reporter. That way I know when I have to manually run the job.
I think you can structure things differently to achieve what you want. Instead of using a Reporter to send a dataset use a Scenario step using Send message. Then have a simple mail reporter that executes when outcome != 'SUCCESS'. That way if your send a dataset Scenario step fails the Reporter will let you know.
