An easy way of making SAP RFC calls from .NET Core

.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

Company Code	Company Name
C001	company 1
C002	Company 2
