Hi,

While trying to run and validate a event in Cognos BI shows following error.

There is no Grammar for uri: http://developer.cognos.com/schemas/report/10.0/.RSV-SRV-0042 Trace back:RSReportService.cpp(759): RSException: CCL_CAUGHT: RSReportService::processImpl()RSReportServiceMethod.cpp(258): RSException: CCL_RETHROW: RSReportServiceMethod::process(): parameterCollectParameterValues_RequestRSASyncExecutionThread.cpp(848): RSException: RSASyncExecutionThread::checkExceptionRSASyncExecutionThread.cpp(305): RSException: CCL_CAUGHT: RSASyncExecutionThread::runImpl(): parameterCollectParameterValues_RequestRSReportDOMBuilder.cpp(266): RSException: CCL_THROW: RSReportDOMBuilder::doParse
