Removing a Data Processing Extension
To remove a data processing extension, simply remove the Extension element for your data processing extension from the configuration file. If you made entries for a report server as well as Report Designer, remove the Extension element from both the RSReportServer.config and RSReportDesigner.config files. After the configuration information is removed, the data processing extension is no longer available to the component.
