    BusinessObjects Enterprise XI Release 2 BIPlatform Web Services Java Consumer ApplicationSchedule a Crystal Report with ParametersThe crystalReport.getPluginProcessingInterface().getReportParameters().getParameters() returns all parameter fields in the report, whether they are used or not.How do you determine whether a parameter is being used in the report?
    Resolution
    Look in the ReportParameterOptions collection to see if ReportParameterOptionEnum.IS_NOT_USED is present.?If it is present, then the parameter is not used in the report.?Sample code:
    　?CrystalReport report = (CrystalReport) infoObjects.getInfoObject(0);　?ReportParameter[] params = report.getPluginProcessingInterface().getReportParameters().getParameters();　?for(int i = 0, m = params.length ; i < m ; i++) {
    　　　?ReportParameter parameter = params[i];
    　　　?ReportParameterOptions reportParameterOptions = parameter.getReportParameterOptions();
    　　　?boolean is_used = true;
    　　　?if(reportParameterOptions != null) {
    　　　　　?ReportParameterOptionEnum[] options = reportParameterOptions.getReportParameterOption();
    　　　　　?for(int j = 0, n = options.length ; j < n ; j++) {
    　　　　　　　?if(ReportParameterOptionEnum.IS_NOT_USED.equals(options[j])) {
    　　　　　　　　　?is_used = false;
    　　　　　　　　　?break;
    　　　　　　　?}
    　　　　　?}
    　　　?}
    　　　?out.println("Is Used: " + is_used +"<BR>");
    　　　?out.println("<BR>");
    　?}
