Connect to SAP

  1. Create an R3Connection object and define all input parameters.
    Make sure to use an SAP dialog user with sufficient SAP authorization, see Authorization Objects - SAP User Rights.

    using (R3Connection con = new R3Connection())
    {
        con.UserName = "SAPUser";
        con.Password = "SAPPassword";
        con.Language = "EN";
        con.Client = "800";
        con.Host = "sap-erp-as05.example.com";
        con.SystemNumber = 00;
        con.Protocol = ClientProtocol.NWRFC; //use ClientProtocol.RFC for classic RFC library
    
        con.Open();
    }
    
    using (R3Connection con = new R3Connection())
    {
        con.UserName = "SAPUser";
        con.Password = "SAPPassword";
        con.Language = "DE";
        con.Client = "800";
        con.MessageServer = "sap-erp-as05.example.com";
        con.LogonGroup = "PUBLIC";
        con.SID = "ECC";
        con.Protocol = ClientProtocol.NWRFC; //use ClientProtocol.RFC for classic RFC library
        con.UsesLoadBalancing = true;
    
        con.Open();
    }
    
    using (R3Connection con = new R3Connection())
    {
        con.UsesWebSocket = true;
        con.WebSocketHost = "myinstance-api.s4hana.cloud.sap";
        con.WebSocketPort = 443;
        con.TlsSettings = new TlsSettings
        {
            TrustAll = false,
            CryptoLibrary = @"C:\lib\sapcrypto.dll",
            ClientPse = "CLIENT.PSE"
        };
    
        con.AliasUser = "TESTUSER",
        con.Password = "Password",
    
        con.Open();
    }
    
  2. Establish the connection using Open().

  3. Run the program to test the SAP connection.
