How can I figure out what process is assigning incidents to our accounts?

Environment

Reports, Audit Log

Issue

After checking the Audit Log, I can see that 'Analytics Report' is assigning incidents to one of our accounts.

Resolution

The below actions from the Audit Log of an incident define a manual process of assigning incidents from a report to a specific account (i.e. right click within the report and select Assign or in-line editing):

The capability of assigning incidents from a report depends on whether the 'Assign' feature is enabled for that report.

Notes

Only staff members that have the appropriate access can assign incidents to other accounts.
