Re-Sending Reports
Occasionally reports will be generated during an outage or other data disruption, meaning that you'd like to regenerate and re-send them.
You have two options in this case - the resend option is for when your reports were generated correctly, but the email itself failed. The regen option is for when your reports failed to generate correctly - usually caused by one of your data sources being unavailable during the scheduled reporting time.
Visual Method
In the Scheduled Tasks addon, you can find the report bundle in the list of scheduled tasks and press Send/Publish Reports.
This will then give you the option of simply re-publishing the reports (leaving them as-they-are and simply sending them again), and regenerating the reports (making new reports).
Manual Method
You can manually send reports using a URL with specific parameters. See the the section on Scheduling Your Reports. This covers how to manually trigger update.
