Why are roles and permissions important?
Roles and permissions are how NetSuite controls what functions or records a user can or can't access. A role is defined as a compilation of permissions or restrictions; permissions and restrictions are usually given around the functional role of each user. Each user is granted access to NetSuite with a specific role(s). From an administration point of view, permissions can be changed at a role level instead of for each individual user, making it easy to manage permissions for groups of users.
