Change datasource of Crystal Report via code

Question

Hi all!
I'm developing partner solution for SAP B1 8.8 in C# and prepared some nice crystal reports. But they are bound to my default database for now. I want to include them to my installation file and change saved datasource location (Server, Company Name, User name, User password) in my installation script as soon as I get this values, entered by user. But I don't know the way how to change datasource in rpt file. I've tried the following:
using CrystalDecisions.CrystalReports.Engine;
ReportDocument rDoc = new ReportDocument();
rDoc.Load(@"C:\Temp\Report2.rpt");
rDoc.DataSourceConnections[0].SetConnection("Server", "SBOTest", "manager", "manager");
rDoc.SaveAs(@"C:\Temp\Report3.rpt");
rDoc.Close();
but it save no changes to rpt file.
I think, this thread belongs mostly to Development/SDK thread, because here most of the people make programs and potentially met this problem in the past.

public void SetCrystalLogin(string sUser, string sPassword, string sServer, string sCompanyDB, CrystalDecisions.CrystalReports.Engine.ReportDocument oRpt)
            CrystalDecisions.Shared.ConnectionInfo oConnectInfo = new CrystalDecisions.Shared.ConnectionInfo();
            oConnectInfo.DatabaseName = sCompanyDB;
            oConnectInfo.ServerName = sServer;
            oConnectInfo.UserID = sUser;
            oConnectInfo.Password = sPassword;
            // Set the logon credentials for all tables
            SetCrystalTablesLogin(oConnectInfo, oRpt.Database.Tables);
            // Check for subreports
            foreach (CrystalDecisions.CrystalReports.Engine.Section oSection in oRpt.ReportDefinition.Sections)
                foreach (CrystalDecisions.CrystalReports.Engine.ReportObject oRptObj in oSection.ReportObjects)
                    if (oRptObj.Kind == CrystalDecisions.Shared.ReportObjectKind.SubreportObject)
                        // This is a subreport so set the logon credentials for this report's tables
                        CrystalDecisions.CrystalReports.Engine.SubreportObject oSubRptObj = oRptObj as CrystalDecisions.CrystalReports.Engine.SubreportObject;
                        // Open the subreport
                        CrystalDecisions.CrystalReports.Engine.ReportDocument oSubRpt = oSubRptObj.OpenSubreport(oSubRptObj.SubreportName);
                        SetCrystalTablesLogin(oConnectInfo, oSubRpt.Database.Tables);
            oRpt.Refresh();
            oRpt.SetDatabaseLogon(sUser, sPassword, sServer, sCompanyDB, false);
            oRpt.VerifyDatabase();
            oRpt.Refresh();
        private void SetCrystalTablesLogin(CrystalDecisions.Shared.ConnectionInfo oConnectInfo, Tables oTables)
            foreach (CrystalDecisions.CrystalReports.Engine.Table oTable in oTables)
                CrystalDecisions.Shared.TableLogOnInfo oLogonInfo = oTable.LogOnInfo;
                oLogonInfo.ConnectionInfo = oConnectInfo;
                oTable.ApplyLogOnInfo(oLogonInfo);
