Hello,
I've been running into this issue quite a few times, and have been unable to solve it through reading various posts/forums. Here is the issue
Software Details:
Datawarehouse Database - SQL Server 2008 R2
Reporting Services Version - SSRS 2008 R2
Development Environment - Visual Studio 2008
Problem Details:
I have been writing reports based of a Relational Datamart with dimensions and facts. The report in question uses dimensions for parameters and facts for content. Multi valued parameters are enabled in the report query by using the 'IN(@Paramenter)' statement within the report query. It has a total of 6 multi-value parameters. I assign the same available values from dimension datasets for each parameter to it's default parameter. Theoretically all the values in the option lists should be selected after first render. This is not always the case.
Example:
SELECT *
FROM dbo.MyTable
WHERE
TableColumn0 IN (@Parameter0)
AND
TableColumn1 IN(@Parameter1)
AND ....N (continue syntax to 6 multi valued parameters)
Some of the multi-value drop down lists are defaulting to have every value selected, and some arenot. The problem is I need to know why some parameters are not selecting all by default when specified.
Thank you in advance for your help.
