The call for a session variable is: VALUEOF("NQ_SESSION.Variable Name") Kurt Wolff, As with dynamic repository variables, session variables obtain their values from initialization blocks. Names for all variables should be unique. To use row-wise initialization, create an initialization block and select the Row-wise initialization option (refer to "Creating Initialization Blocks"). For example, to filter a column on the value of the variable SalesRegion, set the filter to the variable NQ_SESSION.SalesRegion. The Oracle BI Server logs all SQL queries issued to retrieve session variable information if the logging level is set to 2 or higher in the Identity Manager User object, or the LOGLEVEL system session variable is set to 2 or higher in the Variable Manager. Session variables that are not needed during the session do not have their initialization blocks executed.
