New User Role (Management Studio)
Use this page to create an item-level role definition. An item-level role definition is a named collection of tasks that enumerate the tasks a user can perform in relation to folders, reports, models, resources, and shared data sources. An example of an item-level role definition is the predefined Browser role that identifies the kinds of actions a report end user might require for navigating folders and viewing reports.
Role definitions are intended to be few in number. Most organizations only require a few role definitions. However, if the predefined role definitions are insufficient, you can vary them or create new ones.
Role definitions are used only on a report server that runs in native mode. If the report server is configured for SharePoint integration, this page is not available.
