You can then use that session variable as the default date value in your queries for example, Periods.Date = VALUEOF(NQ_SESSION.PREVIOUSSATURDAY). It seems that OBIEE save the default initializer value in the same space than for a repository variable. Dynamic repository values can be set up to do it automatically. This saves the resources which would have been used to execute these unnecessary initialization blocks. This behavior ensures that you cannot use the same connection pool for initialization blocks that you use for queries. Example message: "One of the successors for init block 'A_blk' does not have "Allow deferred execution" flag set.
