Packaging Data Warehouse Reports for Deployment
To install reports into a reporting server folder, use the Report Installer tool (located by default on the Data Warehouse server at %COMMERCE_SERVER_ROOT%\Tools\ReportInstaller.exe).
The reports deployment tool, ReportInstaller.exe gathers all standard and custom reports .rdl files that are contained within subfolders within the path that is specified within the ReportInstaller.exe Path to Commerce Server report files. If you have created custom report .rdl files within the subfolders, the deployment tool will include the report .rdl files within the new reporting folder together with the standard reports supplied with Commerce Server 2009 R2.
