Debug RFC (ABAP) when fired from ACCESS 2010 Application

Hi,

I want to debug the ABAP RFC when fired from a ACCESS 2010 application under WIN 7 64 bit .

I am set following parameters :

With aOg_SAP_Connection

                .client = aMg_SAP_Zugang.Mandant

                .System = aVg_SAP_System_Aktiv

                .ApplicationServer = aMg_SAP_Zugang.ApplicationServer

                .GroupName = aMg_SAP_Zugang.GroupName

                .MessageServer = aMg_SAP_Zugang.MessageServer

                .Systemnumber = aMg_SAP_Zugang.Systemnumber

                .Language = aMs_Chain.Frontend_Language

                .User = aMg_SAP_Zugang.User

                .Password = aMg_SAP_Zugang.Password

                .ABAPDebug = true

                If .LogOn(0, True) Then    'Verbindung zur SAP aufbauen

Fireing .logOn(0, true)  SAP GUI RFC is not starting in ABAP Debug mode to set breakpoints, as in previous SAP Versions. It opens only the SAP Logon 720 application with a modi subwindow. See attached pic. But there I can not set breakpoints in SAP ABAP it seems.

The SAP logon execution in ACCESS does not stop there, but brings the value True. I can run RFC functions now normal, but with no debug function.

Has anybody a answer for my problem.

Thanks for your help & Regards,

Erich Anzböck
