Examples

[C#]

static void Main(string[] args)
{
    R3Connection con = new R3Connection("hamlet",11,"theobald","pw","DE","800");
    con.Open(false);

    // Create a function object
    RFCFunction func = con.CreateFunction("RFC_CUSTOMER_GET");

    Console.WriteLine("Please enter customer number ...");
    Console.WriteLine("(and do not forget the leading zeros ...");

    // fill the export parameter
    StringBuilder CustomerNo =  new StringBuilder(Console.ReadLine());
    func.Exports["KUNNR"].ParamValue = CustomerNo.ToString();

    try 
    {
    func.Execute();
    }
    catch (ERPException e)
    {
        Console.WriteLine(e.Message);
        Console.ReadLine();
        return;
    }

    // Output the result of the function module
    Console.WriteLine("Name of customer:");
    Console.WriteLine(func.Tables["CUSTOMER_T"].Rows[0,"NAME1"]);
    Console.ReadLine();
}

[VB]

Sub Main()
    Dim con As New R3Connection("hamlet", 11, "theobald", "pw", "DE", "800")
    con.Open(False)

    ' Create a function object
    Dim func = con.CreateFunction("RFC_CUSTOMER_GET")

    Console.WriteLine("Please enter customer number ...")
    Console.WriteLine("(and do not forget the leading zeros ...")

    ' fill the export parameter
    Dim CustomerNo As New StringBuilder(Console.ReadLine())
    func.Exports("KUNNR").ParamValue = CustomerNo.ToString()

    Try
        func.Execute()
    Catch e As ERPException
        Console.WriteLine(e.Message)
        Console.ReadLine()
        Return
    End Try

    ' Output the result of the function module
    Console.WriteLine("Name of customer:")
    Console.WriteLine(func.Tables("CUSTOMER_T").Rows(0, "NAME1"))
    Console.ReadLine()
End Sub

Remarks

The following example demonstrates, how to logon, to create a function object and to execute the function

Execute(RFCFunction)

Assigns this connection to the supplied ERPConnect.RFCFunction and then executes the function.

void Execute(RFCFunction function)

Parameters

function RFCFunction

Open()

Opens a connection to an SAP R/3 system.
