When a repository has multiple initialization blocks, you can set the order (establish the precedence) in which the blocks will be initialized. Instead, the Oracle BI Server creates new instances of those variables whenever a user begins a new session. Note that this requirement is waived for internal processes (like Delivers) that use impersonation, if a single user session variable has been associated with the initialization block. This happens automatically when you double-click the variables to paste them into the expression. This tells Oracle BI Presentation Services that these users have identical content filters and security in the Oracle BI Presentation Services.
