Creating variables in BO using BO SDK

Question

Hi,
We can create variables which can be formulas applied on objects using infoview.
Is there any way, these variables can be created using java BO SDK?
Please paste some sample code for us.
Cheers,
Shruti

Please find below a snippet code based on java managed RAS api that adds a formula onto the report. I hope this answer your question.
<%@ include file="logon.jsp"%>
<%
    ReportClientDocument oReportClientDocument;
    IReportAppFactory oReportAppFactory;
    IInfoObjects oInfoObjects=null;
     IInfoObject oInfoObject=null;
     String reportName = "SimpleRCAPIReport.rpt";
    // Retrieve report to be modified
    oInfoObjects = iStore.query("Select * from CI_INFOOBJECTS where SI_PROGID = 'CrystalEnterprise.Report' and SI_INSTANCE = 0 and SI_NAME = '" + reportName + "'");
     oReportAppFactory = (IReportAppFactory)es.getService("", "RASReportService");
     oReportClientDocument = oReportAppFactory.openDocument((IInfoObject)oInfoObjects.get(0), 0, java.util.Locale.ENGLISH);
     // First create the formula field
     FormulaField newFormulaField = new FormulaField();
     //  Set the parameters (assume it's a string and Crystal Syntax)
    newFormulaField.setText("{Customer.Contact First Name} + ' ' + {Customer.Contact Last Name}");
    newFormulaField.setName("CustomerName");
    newFormulaField.setSyntax(FormulaSyntax.crystal);
    newFormulaField.setType(FieldValueType.stringField);
    // Now add it to the report
    oReportClientDocument.getDataDefController().getFormulaFieldController().add(newFormulaField);
     // Now that the formula has been created, add the newly created formula to the report
     // First determine which section to add the formula field to - in this case the details section
     ISection sectionToAddTo = oReportClientDocument.getReportDefController().getReportDefinition().getDetailArea().getSections().getSection(0);
     // Get back all the formulafields in the report
     Fields formulaFields = oReportClientDocument.getDataDefController().getDataDefinition().getFormulaFields();
     int formulaFieldIndex = formulaFields.find("{@CustomerName}", FieldDisplayNameType.formulaName, java.util.Locale.ENGLISH);
     Field formulaField = (Field)formulaFields.getField(formulaFieldIndex);
     // Set the type of field this is
     formulaField.setType(FieldValueType.stringField);
     // Now create a new Field object which will be added to the report
     FieldObject oFieldObject = new FieldObject();
     // Set the datasource of this field object to the formula form of the above Database Field Object
     oFieldObject.setDataSourceName(formulaField.getFormulaForm());
     oFieldObject.setFieldValueType(formulaField.getType());
     // Now set the co-ordinates of where the field will go
     oFieldObject.setLeft(8000);
     oFieldObject.setTop(1);
     oFieldObject.setWidth(1911);
     oFieldObject.setHeight(226);
     // And finally Add it to the report
     oReportClientDocument.getReportDefController().getReportObjectController().add(oFieldObject, sectionToAddTo, -1);
     // Now display the report
   session.setAttribute("reportSource", oReportClientDocument.getReportSource());
   response.sendRedirect("CrystalReportViewer.jsp");
%>
