Boolean Funktion beenden

Dim W_System
Function Attach_Session() As Boolean
Dim il, it
Dim W_conn, W_Sess
If W_System = "" Then
Attach_Session = False
Exit Function
End If
If Not objSess Is Nothing Then
If objSess.Info.SystemName & objSess.Info.Client = W_System Then
Attach_Session = True
Exit Function
End If
End If
If objGui Is Nothing Then
Set SapGuiAuto = GetObject("SAPGUI")
Set objGui = SapGuiAuto.GetScriptingEngine
End If
For il = 0 To objGui.Children.Count - 1
Set W_conn = objGui.Children(il + 0)
For it = 0 To W_conn.Children.Count - 1
Set W_Sess = W_conn.Children(it + 0)
If W_Sess.Info.SystemName & W_Sess.Info.Client = W_System Then
Set objConn = objGui.Children(il + 0)
Set objSess = objConn.Children(it + 0)
Exit For
End If
Next
Next
If objSess Is Nothing Then
MsgBox "No active session to system " + W_System + ", or scripting is not enabled.", vbCritical + vbOKOnly
Attach_Session = False
Exit Function
End If
If IsObject(WScript) Then
WScript.ConnectObject objSess, "on"
WScript.ConnectObject objGui, "on"
End If
Set objSBar = objSess.FindById("wnd[0]/sbar")
objSess.FindById("wnd[0]").Maximize
Attach_Session = True
End Function

So dann wird die Funktion aufgerufen und ein SAP Script teil ausgeführt.
Wie Folgt:

Public Sub BVsHolen()
W_System = "CXT801"
Dim W_Ret       As Boolean
W_Ret = Attach_Session
If Not W_Ret Then
Exit Sub
End If
