I am looking at a system running Navision Application. I am not really looking to go in deep but i just need to know how role assignment for users work. Can users be grouped? I also need to know how the administrative and superuser roles work – how much canone do with these “powers”. Finally, I would liketo know what structures it uses to maintain data (database or flat file?),as well as how to go into the data tables outside of going via the application itself.
