Microsoft distributes Microsoft SQL Server 2012 fixes in one downloadable file. Because the fixes are cumulative, each new release contains all the hotfixes and all the security updates that were included with the previous SQL Server 2012 update release.
This issue applies to the following product:
SQL Server 2012 Reporting Services
Consider the following scenario:
You are running SQL Server 2012 Reporting Services (SSRS 2012) on a computer that has cumulative update package 4 (CU4) for SQL Server 2012 Service Pack 1 (SP1) installed.
You have a report that contains a multivalued parameter. The parameter is configured to accept multiple values.
No default values are configured for the parameters in the report.
You select some parameter values in the report, and then you click View in Report Manager or Report Server.
In this scenario, the report is displayed as a blank page.
Note If the report contains multivalued cascading parameters, the dependent parameters are not populated.
