Master Detail Report - Error

Hi All,

Today i worked on the Master Detail Report. I got some error while creating and running the report. I am confused and validated the report. I got the follwoing error while running the report.

Cognos ReportNet Error:
Master – Detail Report
RSV-SRV-0036
Details: CCLAssertError:0:Fatal: CCL_ASSERT(m_nodeImpl != NULL);

Trace back:
WPBIBusMethod.cpp(201): CCLAssertError: CCL_CAUGHT: WPBIBusMethod::runRequest
WPReportExecutionMethod.cpp(185): CCLAssertError: CCL_RETHROW:WPReportExecutionMethod::checkRequestForExceptions
WPExecuteRequestThread.cpp(169): CCLAssertError: WPExecuteRequestThread::checkException
WPEngine.cpp(1028): CCLAssertError:
WPController.cpp(263): CCLAssertError: CCL_RETHROW: WPController::executeRendering()
LWDataRetrievalEngine.cpp(804): CCLAssertError: CCL_RETHROW: LWDataRetrievalEngine::iterateResultSets
CCLIDOM_Node.cpp(503): CCLAssertError: CCL_THROW:

This is because of not linking the Master and Detail Query properly. Later when i linked those 2 queries properly the error is resolved.

Thanks and Regards,
Soma
