i have a main report that contains some sub report. Each sub report will load data from database via stored procedures and then these sub reports  was added to Main report. I run this report on local sucessfully, but when i deploy on server, it shows error Database logon fail. In my code i have set database connect to database (connection string get from web.config that the same with connection of server). I have a question about this error? Why it run successfully on local, when deploy to server it fail? Does i need to add some lines of code to my class? these is my code:

 ReportDocument rp = new ReportDocument();

//Load report file
rp.Load(ReportHelper.GetReportPath("Report path"));

//Set up connection
rp.SetDatabaseLogon("uid", "pwd", "server","database");

//Add data to Subreport:
rp.OpenSubreport("SubReportName_1").SetDataSource(GetReport_1().Tables[0]); 

rp.OpenSubreport("SubReportName_2").SetDataSource(GetReport_2().Tables[0]); 

//Bind to report viewer
ReportView_1.ReportSource = rp;
ReportView_1.DataBind();
