When the Approval History tab is Enabled via the Approval Global Configuration screen, any action managed by the add-on is logged on the Approval History tab of the JIRA Activity section.
By Default, the Approval History tab looks like as shown below 
:
Displayed data include, by default, the following:
- Source Status
- Transition Name
- Destination Status
- Approval Name
- Approval Detail (any group, project role, user, etc. having been configured on the Approval)
- Executor
- Action (Approved, Rejected, Pending,Automatic Transitioning, Automatic Notification, Approvals Notification, Single Notification)
- Date
- Approver comments
By Default, approval actions are ordered by date in descending order.
Any approval action is persisted on the database only if the Approval History is Enabled.
Any action performed while this setting is disabled cannot be recorded.
The Approval History look can be customized, via the Approval Global Configuration screen, respect to column header visibility,denomination and grouping criteria.
