BIRT Page Level Security option supports page-level security for BIRT designs (.rptdesign). Design developers create a design using security rules that determine which pages or parts of a document a user can view. The design defines a list of users and security roles that can access the document’s groups and sections. In the design, the list can be a static list or an expression that generates a list based on information in the design. iHub uses this list to generate the access control list (ACL) for each document page.
