Problems at calling RFC through Visual Basic

[Former Member]

Hello, I'm connecting to SAP in Visual Basic and i calling a RFC with this code:

Private Sub cmdFunction_Click()

Set dieFunc = FunctionCtrl.Add("KNA1_READ")

dieFunc.Exports("PI_CUSTOMER") = txtcliente.Text

If dieFunc.Call = True Then

'Mostrar resutado

lblSalida.Caption = dieFunc.Imports("PE_KNA1")

Else

MsgBox "Error when accessing function in R/3!"

Screen.MousePointer = vbDefault

Exit Sub

End If

end sub

and diefunc.call always is false.

can somebody help me?

thanks.

If you have a rcent SAPGui (6.20 at least I think), try the External Debugging (Utilities -> Settings -> Debugging) and set a breakpoint (select External).

Good luck!
