The Last Logon Time filter group consists of a time interval filter in the Filter Pane of the Users tab:
With this filter, you can limit the displayed BI data to user accounts that logged on to SAP BusinessObjects on or after a specified date (inclusive), before a date, or in a time interval.
Tip
The last audited action date and time is displayed for any BI object in the Action On column of the Content Area, in a tooltip, and in the Audit History dialog window.
Warning
The date/time of last action in the Action On column may differ from the Audit History window, because Audit History immediately displays the information in real-time which can be newer.
You can cancel this filter by clicking None in the calendar, or by pressing Delete in the field.
