Expired Incidents - Business rules

Summary

Recognizing a new incident created from reply to expired incident

Content

Hi,

I'm looking to create a business rule that would recognize when a new incident is created from a reply to an expired incident.  I see the message "Incident created due to reply to expired incident", but I don't know when that is appended to the incident.

I'd like to set a flag (custom field) to report on when this is happening.

Thanks.
