Back to my When (null) is not Null post, there is a undocumented breaking change in SQL Server 2005 SP2 which you should be aware of. In response to the customer demand, SP2 treats aggregate rows as detail rows. As a result, if the report doesn’t use the Aggregate() function, the report will show all rows. For those using the Aggregate function, there will be no change.
