Using ISCRCommandTable in the Reports Application Server

Question

Hi
We have a report that is linked to a Command but the query may be constructed in different ways (using different tables). In past we've pushed the data to the report but I was looking into pulling the data.
I thought it might be possible to create a Command Object then edit the CommandText Property in code using the RAS API (inproc). Though it's possible to set the CommandText this does not seem to effect the data displayed. Is there a reason for this? Am I doing something wrong?
       Dim mySampleReportPath As String = "C:\Inetpub\wwwroot\SetCommandtext\Report1.rpt"
        rd.Load(mySampleReportPath)
        ' Access the ReportClientDocument API in-process using the ReportDocument class.
        rcd = rd.ReportClientDocument
       'Change SQL in Command.
        Dim c As CrystalDecisions.ReportAppServer.DataDefModel.ISCRCommandTable
        With rcd.DataDefController.Database.Tables
            c = .Item(.FindByAlias("Command"))
            c.CommandText = "SELECT name, '123' as test FROM Checklist"
            rcd.DataDefController.ParameterFieldController.SetCurrentValue("", "test", "USA")
            rcd.DataDefController.ParameterFieldController.SetCurrentValue("", "title", c.CommandText)
        End With
        ' Set the report source of the Crystal Report viewer to the instance of the report.
        myCrystalReportViewer.ReportSource = rd
Cheers
Alex
