Logon failed.Failed to export the report. Error in File .rpt: Unable to connect: incorrect log on parameters.

Hello,

I am using some Crystal Reports in my web application and exporting them as PDF file. The files are developed in Crystal Reports 13_0_2 for Visual Studio 2010. After deploying on server, all reports are working fine expect one.

At the time of export, it is giving following error message:

           Logon failed.Failed to export the report.

           Error in File testing {F282207C-64DC-43E3-8EB8-562E7FB9643E}.rpt:

           Unable to connect: incorrect log on parameters.

For reports I am using XML file as datasource and passing connection through following code.

            PropertyBag logonInfo = new PropertyBag();

            logonInfo.EnsureCapacity(1);

            logonInfo.Add("XML File Path", Server.MapPath("sample.xml"));

            PropertyBag attributes = new PropertyBag();

            attributes.EnsureCapacity(5);

            attributes.Add("Database DLL", "crdb_adoplus.dll");

            attributes.Add("QE_DatabaseType", "ADO.NET (XML)");

            attributes.Add("QE_ServerDescription", "NewDataSet");

            attributes.Add("QE_SQLDB", true);

            attributes.Add("QE_LogonProperties", logonInfo);

            CrystalDecisions.ReportAppServer.DataDefModel.ConnectionInfo connectionInfo = new CrystalDecisions.ReportAppServer.DataDefModel.ConnectionInfo();

            connectionInfo.Kind = CrConnectionInfoKindEnum.crConnectionInfoKindCRQE;

            connectionInfo.Attributes = attributes;

I don't get the issue, all reports are same and other reports are working fine, I am able to download them as PDF file except one report. What should I do, any idea?

Regards,

Namrata
