Bex doesnu00B4t get Link from RFC

Hello everyone,

i have a problem with a RFC Call and BEX. Bex should open a Link which It get back from a RFC.

Following activity constellation.

Bex open a Connection to a RFC. The RFC call a defined Application (Webdynpro Applikation) and look for the Url of the Application. Then Bex get this Url back from RFC. Bex should open this URL. The Problem is it doesn´t works and I don´t know why. BEx say´s no error (The Programm run´s, but Bex get not back the Url from the RFC).

>The RFC has the 'remote status'.

VBA Code

SAP Connection

...........

If sapConnection.Logon(0, False) <> True Then

MsgBox "Keine Verbindung zum R/3!"

Else

Set theFunc = functionCtrl.Add("SS_RFC_URL_TEST")

objQueryTab = "200"

'theFunc.Exports("E_PAR") = objQueryTab

theFunc.Exports("I_PAR") = objQueryTab

sReturn = theFunc.call

If sReturn = True Then

objQueryTab = theFunc.Imports("E_PAR")

End If

sapConnection.logoff

End If

End Sub
