How to give Roles to users in NAV

Hi Friends

I just want to help me on this Issue. If there is any functionality in NAV 5.O where you can trace the users while they are doing their daily job and find out which objects they affected . so that it can help me in creating roles for users based on that .

Thanks

why not ask them what they do and decipher from that?

right but Is there any functionality on NAV to deal with this issue

thanks
