The audit shield provides a quick view of a record's major audit details without having to access the Audit History tab.
The audit shield is available on each major tab of the record. You can hold your mouse over the shield to display the record's Created By Date/Time, Created By User ID, Last Modified by Date/Time, and Last Modified By User ID.
On main forms, the audit shield can be found in the right-hand corner of the form.
The audit shield can also be found on sub-form entries, like involved persons, identifying changes to specific sections.
