query engine error

"query engine error" in ...4trerf-fr454-5453-ffftre4.rpt"
Usually what is the problem when i get this message error,when is loading a report into a reportviewer?
thanksThis may be due to the improper link between the tables used. Check for the link between the tables properly.

Ashok|||I am have 7 reports in my app and none of my reports work on the deployment machine. Could there be anything else wrong with it? It works fine on my dev machine.

Query Engine Error

Hi All,

I am trying to build an application in VS.Net which uses Crystal Report 11 to build the rpt file. I have an XML and XSD file as my datasources. I want to view the report in PDF format. Now my source code looks like:

ReportDocument doc = new ReportDocument();
string fileName = Server.MapPath("MyReport.rpt");
doc.Load(fileName);

DataSet ds = new DataSet();
ds.ReadXml(Server.MapPath("MyXML.xml"));

doc.SetDataSource(ds);

ExportOptions exportOpts = doc.ExportOptions;
exportOpts.ExportFormatType = ExportFormatType.PortableDocFormat;
exportOpts.ExportDestinationType = ExportDestinationType.DiskFile;
exportOpts.DestinationOptions = new DiskFileDestinationOptions();

DiskFileDestinationOptions diskOpts = new DiskFileDestinationOptions();
((DiskFileDestinationOptions)doc.ExportOptions.DestinationOptions).DiskFileName = Server.MapPath("MyPDF.pdf");

doc.Export();

But it gives me the error
"Query Engine Error: 'c:\inetpub\wwwroot\MyWebsite\MyReport.rpt'"

I tried out all the forums but could not find any solution. Someone told me that it is due to xsd file error. But in Crystal Report it is running perfectly OK. Can anyone help.did you figure out what happened? I am getting this error during my deployment, but on my local PC it works fine.
