Audit Trail Subtab
By default, you are able to view audit trail records only for saved searches, reports, and report schedules that you own. To view audit trail records for saved searches, reports, and report schedules owned by other users, you need to have the Administrator role or the Unrestricted Analytics Audit Trail permission.
The Audit Trail Subtab lists all audited changes and actions for the respective Saved Search, Saved Report, or Report Schedule.

The default columns displayed are as follows:
-
Date: the date and time the change was made.
-
Set By: the user who made the change.
-
Component Action: the action taken (update, delete, or create).
-
Component Type: the type of page component that was edited.
-
Component Name: the name of the edited page component.

Understanding Audit Trail Data
The Audit Trail offers a rich selection of data that can be used to gather a detailed understanding about the changes made. In the example below two changes were made to a saved search.
-
The Public box was unmarked. This change registered 2 changes in the Audit Trail.
-
The Search Options component type was updated from value=T to value=F.
-
The component type Audience was updated from value=T to value=F.
In effect the value for the Audience Search Option was changed from true to false.
-
-
The Public box was marked again. This change also registered 2 changes in the Audit Trail -the reverse of the previous changes.

Tips
-
A single user action can create a series of cascading events in the audit trail. When reading audit trail data it is useful to group actions by date and time. Actions with the same time are most probably a single action.
-
Customize the audit view to increase your understanding of what events took place.
-
Focus on the key data that you need. Are you searching for the new and old values, or are you more concerned with who made the change?
