Connecting SAP system from C# application via .NET Connector 3.0

Connecting to an SAP system from a C# application requires configuring the .NET Connector 3.0 with proper connection parameters. The configuration can be defined in your application's app.config or web.config file.

Configuration Setup

You can configure the SAP connection using the following XML configuration ?

<SAP.Middleware.Connector>
   <ClientSettings>
      <DestinationConfiguration>
         <destinations>
            <add NAME="Name" USER="User" PASSWD="orly" CLIENT="100" LANG="EN"
                 ASHOST="host.domain.com" SYSNR="70" MAX_POOL_SIZE="10" IDLE_TIMEOUT="20"
                 SNC_PARTNERNAME="p:CN=mycn.com, OU=A, O=B, L=C, C=GB"
                 SNC_MYNAME="p:CN=myname.com, C=GB, O=A, OU=B"
                 SNC_QOP="8" SNC_MODE="8" TRACE="2"/>
         </destinations>
      </DestinationConfiguration>
   </ClientSettings>
</SAP.Middleware.Connector>

Configuration Parameters

The key parameters in this configuration include ?

• NAME ? Destination name for identifying the connection
• USER/PASSWD ? SAP system credentials
• CLIENT ? SAP client number (e.g., 100)
• ASHOST ? Application server hostname
• SYSNR ? System number
• SNC_PARTNERNAME/SNC_MYNAME ? Secure Network Communication certificates
• MAX_POOL_SIZE ? Maximum connection pool size
• IDLE_TIMEOUT ? Connection idle timeout in seconds

Example Usage

After configuration, you can establish the connection in your C# code ?

using SAP.Middleware.Connector;

class Program
{
    static void Main()
    {
        try
        {
            RfcDestination destination = RfcDestinationManager.GetDestination("Name");
            Console.WriteLine("Connected to SAP system: " + destination.SystemAttributes.SystemID);
        }
        catch (RfcCommunicationException ex)
        {
            Console.WriteLine("Connection failed: " + ex.Message);
        }
    }
}

The output of successful connection will be ?

Connected to SAP system: [SystemID]

Conclusion

The .NET Connector 3.0 provides a straightforward way to connect C# applications to SAP systems through XML configuration and simple API calls. Proper configuration of connection parameters and security settings ensures reliable communication with your SAP environment.
