ITSM - Sent email notification on priority change

Hello Friends,

I am working on SAP Solution Manager 7.1 SP14. I am configuring ITSM - incident management, I have requirement of sent automatic email notification to reporter when priority of Incident get change.

In standard action SMIN_STD_MAIL_REPORTER there is condition object STATUS_CHANGE, which I use to detect change in Status of incident.

Is there any way to find-out change in Priority and sent email to reporter.

Thanks,

Sunny
