Access to views in SAP Service Cloud V2 is restricted using business roles. Business roles define the permissions and access rights for users, including which views (e.g., case lists, account details) they can access. According to SAP documentation, "Business roles are used to control access to specific views and objects, ensuring users only see relevant data." Determination rules (B) are used for field value calculations, not view access. Code list restrictions (C) limit dropdown values, not views. Field attributes (D) control field properties, not view-level access.
