Hello @Nisha Mishra23 ,

If you just need to know how many times an Incident was reassigned then simply include the "Reassignment count" field in your report:

If you need more information you can create the report on the incident_metric view, with the filter Definition = Assignment group. It will show which groups the Incidents have been assigned to, when, and how long.

Regards,

Robert
