FIX: A parameter value is replaced by its default value when the parameter is hidden and in a snapshot report in SQL Server 2008 Reporting Services

Consider the following scenario:

• You have a computer that is running Microsoft SQL Server 2008 Reporting Services.
• You have a report that has two parameters.One parameter is hidden, and the other parameter is visible. Both parameters have a default value.
• You create a snapshot for the report.
• You run the report as a report snapshot by passing in nondefault values to both report parameters. You see that the report correctly shows the values that are passed.
• You click the View Report button in the report.

In this scenario, you find that the visible parameter uses the nondefault value. However, you find that the hidden parameter uses the default value.

The fix for this issue was first released in Cumulative Update 7 for SQL Server 2008 Service Pack 1. For more information about this cumulative update package, click the following article number to view the article in the Microsoft Knowledge Base:Note Because the builds are cumulative, each new fix release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2008 fix release. We recommend that you consider applying the most recent fix release that contains this hotfix. For more information, click the following article number to view the article in the Microsoft Knowledge Base: Microsoft SQL Server 2008 hotfixes are created for specific SQL Server service packs. You must apply a SQL Server 2008 Service Pack 1 hotfix to an installation of SQL Server 2008 Service Pack 1. By default, any hotfix that is provided in a SQL Server service pack is included in the next SQL Server service pack.

To work around this issue, you can use one of following methods:

Method 1

Run reports by configuring the parameters in the URL that is created by Report Manager for the report, and then open this URL in a browser. Do this instead of clicking the View Report button in the report.

Method 2

Do not use hidden parameters.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
