ARC admin data security is automatically set for a user. Is it a functionality of ARC?
The data security will not get set for any user automatically unless some one specifically assigns it. Also, if the tables related to security are fiddled manually then the security might get assigned. There are 4 tables related to security that resides in WH. They are ADMIN_USER_STORE, ADMIN_ROLE_STORE, ADMIN_USER_DEPARTMENT and ADMIN_ROLE_DEPARTMENT. If any of these tables are fiddled manually then, there might be chances of the data security get assigned to the User.
