View-Level Access Control
Organizations are generally arranged around functions, with employees being assigned one or more functions. View-level access control determines what parts of a Siebel application a user can access. This access is based on the functions assigned to that user. In Siebel CRM, these functions are called responsibilities. Responsibilities define the collection of views to which a user has access. Each user's primary responsibility also controls the user's default screen tab layout and tasks.
You can choose to store users’ Siebel responsibilities as roles in a directory attribute instead of in the Siebel database if you are using LDAP or custom security adapters, or if you are using Web SSO authentication.
