An easy way of making SAP RFC calls from .NET. Libray is supported in Windows, Linux and macOS.
-
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
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(userName, password, hostname, client))
{
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 |
Included samples in project
- List FI Comapnies
- List FI Customers
- Get Details of a FI Customer
- FI General Ledger Account
Alternatively it's possible to sign-on with SSO instead of user and password.
Example : Opening a RFC connection using NTLM.
var conn = new RfcConnection(
hostname: "server_name",
client: "000",
sncPartnername: @"p:DOMAIN\SRVACC",
sncLib: @"gx64ntlm.dll" )Define the SNC parameters related to your environment. If SncLib is not defined, NetWeaver RFC Library uses library defined in environment variable SNC_LIB or SNC_LIB_64.
public string SncQop { get ; set; }
public string SncMyname { get; set; }
public string SncPartnername { get; set; }
public string SncLib { get; set; }
