Recieve IDOCs via this Library

[jogibear9988]

We used the sapnco.dll before in our SAP connector.
Within this we had a class like this:

public class ServerHandler
{
    [RfcServerFunction(Name = "STFC_CONNECTION")]
    public static void StfcConnection(RfcServerContext context, IRfcFunction function)
    {
        }


    [RfcServerFunction(Name = "IDOC_INBOUND_ASYNCHRONOUS", Default = false)]
    public void IdocInboundAsynchronous(RfcServerContext context, IRfcFunction function)
    {
       
    }
}

and this functions where then called from SAP Side.
Is this also possible with this library?

And also we send IDOCs with code like this:

    public void SendTestIdoc()
    {
            RfcRepository repo = _sapClient.Repository;
            IRfcFunction bapi = repo.CreateFunction("IDOC_INBOUND_ASYNCHRONOUS");
            var controlTable = bapi.GetTable("IDOC_CONTROL_REC_40");

            IRfcStructure controlStructure = controlTable.Metadata.LineType.CreateStructure();

            controlStructure.SetValue("TABNAM", "EDI_DC40");
            controlStructure.SetValue("MANDT", IdocConfig.MANDT);

            var dataTable = bapi.GetTable("IDOC_DATA_REC_40");

            IRfcStructure dataStructure = dataTable.Metadata.LineType.CreateStructure();

            dataStructure.SetValue("SEGNAM", "E2LINFX");
            dataStructure.SetValue("SDATA", "001Test");

            dataTable.Insert(dataStructure);

            bapi.SetValue("IDOC_DATA_REC_40", dataTable);

            bapi.Invoke(_sapClient);
    }

also possible???

and one more, with the old SAP Library we need to set up multiple config setting:
Don't we need all of them?

ClientConfig:

            { RfcConfigParameters.SystemID,  _sap.ClientConfig.SystemID },
            { RfcConfigParameters.Client,  _sap.ClientConfig.Client },
            { RfcConfigParameters.Language,  _sap.ClientConfig.Language },
            { RfcConfigParameters.PoolSize, "5" },
            { RfcConfigParameters.PeakConnectionsLimit, "10" },
            { RfcConfigParameters.IdleTimeout, "600" },
            { RfcConfigParameters.User, _sap.ClientConfig.User },
            { RfcConfigParameters.Password, _sap.ClientConfig.Password) },
            { RfcConfigParameters.MessageServerHost, _sap.ClientConfig.MessageServerHost);
            { RfcConfigParameters.MessageServerService, _sap.ClientConfig.MessageServerService);
           { RfcConfigParameters.LogonGroup, _sap.ClientConfig.LogonGroup);
            { RfcConfigParameters.AppServerHost, _sap.ClientConfig.AppServerHost);
          {  RfcConfigParameters.SystemNumber,  _sap.ClientConfig.SystemNumber );
          { RfcConfigParameters.GatewayHost, _sap.ClientConfig.GatewayHost);

ServerConfig:

            { RfcConfigParameters.RepositoryDestination,  _sap.ServerConfig.RepositoryDestination },
            { RfcConfigParameters.GatewayHost, _sap.ServerConfig.GatewayHost },
            { RfcConfigParameters.GatewayService, _sap.ServerConfig.GatewayService },
            { RfcConfigParameters.ProgramID,_sap.ServerConfig.ProgramID },
            { RfcConfigParameters.RegistrationCount, "1" }

Hi,

the latest release candidate (https://www.nuget.org/packages/Dbosoft.YaNco/4.3.0-rc.1) adds support for RFC servers.

A sample can be found here (https://github.com/dbosoft/YaNco/blob/main/test/RfcServerTest/Program.cs).

Have a look at the samples and if you implement a working idoc receiver I would be happy about a PR with a reference implementation of a idoc receiver.

The config required is similar as in sapnco as you have to configure always the same settings for a SAP connection.
A RFC server registers in a SAP gateway and therefore has to specify the connection to it.
A client is not needed for server only registration, however in that case metadata cannot be retrieved from the sap system and no response can be send back asynchronously. So normally a RFC server will also have a client connection.

Best Regards,
Frank

There is now a sample implementation of a IDoc receiver in this project: https://github.com/dbosoft/YaNco/tree/main/samples/net6.0/ExportMATMAS
