.NET client library for SAP NetWeaver RFC

An easy way of making SAP RFC calls from .NET. Libray is supported in Windows, Linux and macOS.

Supported Platforms & Prerequisites

• Requires .NET Framework ( .NET Standard 2.0 or higher )

  • .NET Framework 4.6.1 or higher
  • .NET Core 2.0 or higher

• OS versions

  • Windows x64.
  • Redhat Linux 7 or other Linux distribution that is supported simultaneously by .NET Core and SAP NetWeaver RFC.
  • macOS 10.12+.

• SAP NetWeaver RFC Library 7.50 SDK C++ binaries must be installed locally. For download and installation instructions check SAP Note 2573790

Using this package

Add the package using the dotnet cli:

$ dotnet add package NwRfcNet

Create a class to match SAP RFC parameters

    public class BapiCompanyOutputParameters
    {
        public CompanyDetails[] Details { get; set; }
    }

    public class CompanyDetails
    {
        public string CompanyCode { get; set; }

        public string Name { get; set; }
    }

Map RFC mapameters to class

    RfcMapper mapper = new RfcMapper();

    mapper.Parameter<BapiCompanyOutputParameters>().Property(x => x.Details)
        .HasParameterName("COMPANYCODE_LIST")
        .HasParameterType(RfcFieldType.Table);

    mapper.Parameter<CompanyDetails>().Property(x => x.CompanyCode)
        .HasParameterName("COMP_CODE")
        .MaxLength(4)
        .HasParameterType(RfcFieldType.Char);

    mapper.Parameter<CompanyDetails>().Property(x => x.Name)
        .HasParameterName("COMP_NAME")
        .MaxLength(25)
        .HasParameterType(RfcFieldType.Char);

Open a connection to server and invoke a BAPI

    using (var conn = new RfcConnection(builder => builder
        .UseConnectionHost("hostname")
        .UseLogonUserName("user")
        .UseLogonPassword("password")
        .UseLogonClient("cln")))
    {
        conn.Open();
        using(var func = conn.CallRfcFunction("BAPI_COMPANYCODE_GETLIST"))
        {
            func.Invoke();
        }
    }

or

    using (var conn = new RfcConnection("Server=server_name;lang=en;user=testUser;pwd=secret"))
    {
        conn.Open();
        using(var func = _conn.CallRfcFunction("BAPI_COMPANYCODE_GETLIST"))
        {
            func.Invoke();
        }
    }

Get result and display to Console

    var returnValue =  func.GetOutputParameters<BapiCompanyOutputParameters>();
    Console.WriteLine(String.Format("|{0,-20}|{1,-10}", "Company Code", "Company Name"));
    foreach (var row in returnValue.Details)
    {
        Console.WriteLine(String.Format("|{0,-20}|{1,-10}", row.CompanyCode, row.Name));
    }

Output should be
