In an existing ssrs 2012 report, I want to basically add the following logic to a new dataset that will be used by a new parameter called 'Inventory'.SELECT DISTINCT Inv_number as value, Inv_name as labelFROM s.dbo.fnUser( @endYear, 0, 0, 0)WHERE (@report is not null)order by label,valueIn this ssrs report, there are 15 reports that can automatically be generated. I basically want this new parameter called 'Inventory' to only be activewhen the 4th report is selected to be generated. Thus in the query I listed above, how can I change the query to only be active when the 4th report is selected?I tried to change the where clause to (@report(4) is not null), but that did not work. Thus can you show me the sql I can use to accomplish my goal?
