New Role Assignment / Edit Role Assignment Page (Report Manager)
Use the New Role Assignment or Edit Role Assignment page to grant permissions to report server items and operations. Each user who requires access to a report server must have a role assignment that defines the level of access. You can create role assignments at the root node, or on a specific report, model, folder, resource, or shared data source. Reporting Services security is enforced through role assignments that you apply to items. A role assignment matches a group or user to a role definition, where each role definition identifies the tasks that groups or users can perform with regards to a specific item.
To open this page, select any item, click the Properties tab at the top of the page, and then click the Security tab at the side of the page. You must have permission to set security at the item level. If an item currently inherits security from a parent item, click Edit Item Security to change the security settings.
Item-level role assignments can have a broad impact. Although they can be associated with a single report or folder, they can also be defined at a high level in the folder hierarchy and be inherited by folders and items that are lower in the tree.
