关于cognos导出数据问题

发现我做数据分析时，如果维度涉及七个（含）以上，就无法导出excel，总是会出错，如下：
RSV-SRV-0040

      应用程序出错。请与管理员联系。


CCLAssertError:0:Fatal: CCL_ASSERT(m_valuesVector.size() <= CCL_uint8_MAX);RSV-SRV-0042 回溯：RSReportService.cpp(802): CCLAssertError: CCL_CAUGHT: RSReportService::process()RSReportServiceMethod.cpp(239): CCLAssertError: CCL_RETHROW: RSReportServiceMethod::process(): asynchWait_RequestRSASyncExecutionThread.cpp(774): CCLAssertError: RSASyncExecutionThread::checkExceptionRSASyncExecutionThread.cpp(211): CCLAssertError: CCL_CAUGHT: RSASyncExecutionThread::run(): asynchRunSpecification_RequestRSASyncExecutionThread.cpp(824): CCLAssertError: CCL_RETHROW: RSASyncExecutionThread::processCommand(): asynchRunSpecification_RequestExecution/RSRenderExecution.cpp(593): CCLAssertError: CCL_RETHROW: RSRenderExecution::executeExecution/RSRenderExecution.cpp(656): CCLAssertError: CCL_RETHROW: RSRenderExecution::executeRSQueryMgr.cpp(1051): CCLAssertError: CCL_RETHROW: RSQueryMgr::getResultSetIteratorRSQueryMgr.cpp(1211): CCLAssertError: CCL_RETHROW: RSQueryMgr::createIteratorRSQueryMgr.cpp(1189): CCLAssertError: CCL_RETHROW: RSQueryItem.cpp(92): CCLAssertError: CCL_THROW:

但如果我将维度缩减到六个或以下，即导出是正常的，这个是否有地方设置？
