looking into login information for last 60 days

Hi,

Is there  a way , I can find out who logged into SAP BOBIP in last 60 days. If I log into the CMC, and I look into the session, I can see who are logged in currently. But I want to find out who were logged in in past 60 days . I went to the Auditing section, and under the common event, both "logon" and "logout" are checked. I just want to know where I can find "who were logged in in past 60 days" .

Thanks
