用RFC_CALL_TRANSACTION RFC VB捕获数据

Question

我变成了一个错误代码1001，一个SAP远程错误？

我搜索了很多但什么也没找到。也许有人知道这里有什么问题。我正在使用SAP 720。

Microsoft.VisualBasic.CompilerServices.LateBinding.LateGet(Object (0x000003E9)：SAP函数调用bei Microsoft.VisualBasic.CompilerServices.NewLateBinding.LateGet(Object o、Type objType、String name、Object[] args、String[]参数、Boolean[] CopyBack) System.Runtime.InteropServices.COMException实例、类型、字符串MemberName、Object[]参数、String[] ArgumentNames、Type[] TypeArguments、Boolean[] CopyBack)。

这是我的代码：

    Public FunctionCtrl As Object
    Function login_Call()
    Try

        Dim conn As Object
        FunctionCtrl = CreateObject("SAP.Functions")
        conn = FunctionCtrl.Connection


        conn.System = XXX
        conn.ApplicationServer = XXX
        conn.SystemNumber = XXX
        conn.Client = "XXX"
        conn.user = XXX
        conn.Password = XXX
        conn.Language = XXX
        'needed for frontend dialog
        conn.RfcWithDialog = True

        'log on with logon dialog
        If Not conn.Logon(0, 1) Then
            Dim WsShell
            Dim intText As Integer
            WsShell = CreateObject("WScript.Shell")
            intText = WsShell.Popup("Logon not succesful." & vbCrLf & _
                               "will be closed automatically in one minute...", 60)
            'conn = Nothing
            Anmeldung_Call = False
            Exit Function
        End If
        Anmeldung_Call = True

    Catch ex As Exception

        Anmeldung_Call = False
    End Try
    Me.Text = DateTime.Now.ToString()
End Function

Sub Open_IW73()
    Dim BdcTable As Object
    Dim RfcCallTransaction As Object
    Dim Messages As Object
    Dim count As Integer

    'call transaction IW73
    RfcCallTransaction = FunctionCtrl.Add("RFC_CALL_TRANSACTION")
    RfcCallTransaction.Exports("TRANCODE") = "IW73"
    RfcCallTransaction.Exports("UPDMODE") = "S"
    BdcTable = RfcCallTransaction.Tables("BDCTABLE").....

错误出现在以下一行："RfcCallTransaction = FunctionCtrl.Add("RFC_CALL_TRANSACTION") "“

谢谢

我也犯过同样的错误。人们建议使用不同的修复方法，比如使用SAP.functions.Unicode。为我做了什么，只是简单地改为"RFC_CALL_TRANSACTION_USING“。我不确定这些命令之间的确切区别，所以要小心。但到目前为止，它一直在为我工作。
