AS400 Finding which users logged on interactively

Hi can anyone enlighten me if it's difficult to find back which interactive user sessions that were active during a certain timeframe?

I am working in a multi national environment where we have users from several countries active on the same AS400 and i want to narrow it down so i can select only the users from one location.

I was wondering if you can select it somehow based on the country identifier in the user's profile and if you have to have full blown secadm for that or not because i have elevated rights but i'm not secadm

Country or region identifier . . . . . . . : BE

I already browsed a bit on the web but the thing i found is by far not specific enough ( displaying the log contents & selecting all logon & logoff events )
