The admin user created the processes. Each process is supposed to "autostart" only for users belonging to respective user groups. And this works alright for all 'normal' users.
However when a user with admin rights (user belongs to Application Administrator, PMO System Administrator groups etcc)
submits timesheets , all the above process gets "autostarted" .
When i checked the global rights for this user.. There is no Process Autostart - All rights. No rights in Instance also.
So I guess, I will have to remove some admin rights from this user, but not able to find which admin group to remove him from.
