How to login to SAP using RFC user credentials

[Former Member]

  Hi,

  I usually login to SAP from my .net application by creating an instance of SAP Logon control and passing the credentials(dialogue user credentials).

                tObjType = Type.GetTypeFromProgID("SAP.LogonControl.1");                

                oLoginCtrl = Activator.CreateInstance(tObjType);

But now I have a scenario like the customer wants my application to use RFC user credentials which will not work if I use SAP Logon control.

Is there any other way to login to SAP using RFC credentials?

Thanks in advance

Hi Manosh,

I have on hand just the VB code below. For C#, however, the idea shall be obvious... Instead of "SAP.Functions.Unicode" you may use also "SAP.Functions" if you do not expect issues with code pages.

Set r3 = CreateObject("SAP.Functions.Unicode")

  r3.Connection.ApplicationServer = "server.ip"
  r3.Connection.SystemNumber = "00" ' Put your system number
  r3.Connection.User = "Username"
  r3.Connection.Password = "Password"
  r3.Connection.Client = "010" ' Put your client number

  r3.Connection.Language = "EN"

Dim silent As Boolean
silent = True
' Put silent = False if you want a password pop up for debugging
  If r3.Connection.Logon(0, silent)  Then
     Set func = r3.Add("BAPI_FUNCTION")
     func.Call
  End If

Btw. for new application I recommend to switch over to .NET Connector. In the end it's much simpler to use and you can get much more out of it. And it's managed code.

Hi,

Thank you very much Hynek Petrak. It worked for me. I am pasting my code here.

tObjType = Type.GetTypeFromProgID("SAP.Functions");

oLoginCtrl = Activator.CreateInstance(tObjType);

_oSAPCon = oLoginCtrl.GetType().InvokeMember("Connection", BindingFlags.InvokeMethod, null, oLoginCtrl, null);

I have been trying .NET Connector for a while. I will move to the same soon.

Sorry I took a little time to get back.

Hi

Thank you  Hynek Petrak,

Switch over to .NET Connector means SAP Netweaver Gateway ?

Hello Manosh,

no, it means to switch over what is described in the blog located here:
