Should assign analytic privilege to Role or User?

Hi there,

I have created a dynamic analytic privilege, and i am assigning it to a role. so analytic privilege is getting assigned to SYSTEM user also. But for system user i haven't assigned the role but some how it got assigned and i am not able revoke the role from system user.

So to solve this i have removed analytic privilege from role and assigning it to users manually.

Is it the way hana works or i am missing something???
