Ssrs report web service to save report as pdf throws error Soap exception unhandeled by user code

Question

I am creating a C# web application to save  an SSRS report as a pdf file on my local machine.
I added the ReportService web reference as RS2005 and ReportExecution2005 web reference as RE2005.
http://myServer/ReportServer_DEVPROJECT/ReportExecution2005.asmx?WSDL
http://myServer/ReportServer_DEVPROJECT/ReportService2005.asmx?WSDL
I created the following function SaveReport that is called on button click. My report can be accessed on the report server with the following url:
http://myServer/Reports_DEVPROJECT/Pages/Report.aspx?ItemPath=%2fData+Mgmt%2fSample+Letter
On the Report Manager home page the report link appears as "SAMPLE LETTER".
It is deployed in the DataMgmt folder on the Report Manager.
It uses a data source called "DS Letter" with option "Credentials stored securely in the report server"
My application gets compiled, but I get the following run time error:
Error: Soap exception unhandeled by user code. The item '/DataMgmt/Sample Letter' cannot be found. ---> Microsoft.ReportingService
s.Diagnostics.Utilities.ItemNotFoundException: The item '/DataMgmt/Sample Letter' cannot be found.
Please check my code and let me know what I can do to run this successfully. Once this is done, I would like to get help with passing a parameter (memberID) to the generate report for that member, through this application.
Thank You in advance for your help.
public static void SaveReport()
RS2005.ReportingService2005 rs;
RE2005.ReportExecutionService rsExec;
// Create a new proxy to the web service
rs = new RS2005.ReportingService2005();
rsExec = new RE2005.ReportExecutionService();
// Authenticate to the Web service using Windows credentials
rs.Credentials = System.Net.CredentialCache.DefaultCredentials;
rsExec.Credentials = System.Net.CredentialCache.DefaultCredentials;
rs.Url = "http://myServer/ReportServer_DEVPROJECT/ReportService2005.asmx";
rsExec.Url = "http://myServer/ReportServer_DEVPROJECT/ReportExecution2005.asmx";
string historyID = null;
string deviceInfo = null;
string format = "pdf";
Byte[] results;
string encoding = String.Empty;
string mimeType = String.Empty;
string extension = String.Empty;
RE2005.Warning[] warnings = null;
string[] streamIDs = null;
string fileName = @"c:\temp\samplerHAPeport.pdf";
string _reportName = @"/DataMgmt/Sample HAP Letter";
string _historyID = null;
bool _forRendering = false;
RS2005.ParameterValue[] _values = null;
RS2005.DataSourceCredentials[] _credentials = null;
RS2005.ReportParameter[] _parameters = null;
try
_parameters = rs.GetReportParameters(_reportName, _historyID, _forRendering, _values, _credentials);
RE2005.ExecutionInfo ei = rsExec.LoadReport(_reportName, historyID);
RE2005.ParameterValue[] parameters = new RE2005.ParameterValue[1];
if (_parameters.Length > 0)
//parameters[0] = new RE2005.ParameterValue();
//parameters[0].Label = "";
//parameters[0].Name = "";
//parameters[0].Value = "";
rsExec.SetExecutionParameters(parameters, "en-us");
results = rsExec.Render(format, deviceInfo,
out extension, out encoding,
out mimeType, out warnings, out streamIDs);
using (FileStream stream = File.OpenWrite(fileName))
stream.Write(results, 0, results.Length);
catch (Exception ex)
throw ex;
protected void BtnGenReport_Click(object sender, EventArgs e)
SaveReport();

Hello Devster,
Thank you to post your question on TechNet forum.
After reviewing the whole post, I have a question to you. You can access the report via the link, http://myServer/Reports_DEVPROJECT/Pages/Report.aspx?ItemPath=%2fData+Mgmt%2fSample+Letter.
From the URL, I can see that the report is located at: /Data Mgmt/Sample Letter, instead of /DataMgmt/Sample Letter. In addition, I found that the target report is "/DataMgmt/Sample HAP Letter" instead of "/DataMgmt/Sample Letter" as the error described. I
am not sure whether you post out the correct code segment.
Please check the above things on your side, and hope it is helpful to you.
Regards,
Edward
