Using the code for connection to RFC from VB, we are accessing several RFCs, thus we created a Web Service which stayed at IIS.
In development works perfectly running locally, however when uploading to IIS server, presents the error System.Exception: Cannot create ActiveX component.
System.Exception: Cannot create ActiveX component.

Being:
line 15 this line is inside the method RFC_CONECTION1
functionCtrl = CreateObject("SAP.Functions")
line 330 this line is inside the method ServicioDisponible
RFC_CONECTION1(0)
line 40 this line is inside the web method that gives the error
Dim response As ServicioDisponibleRes = convenio.ServicioDisponible()
Apparently just the application does not have access to SAP dll, or missing any permission from IIS, I tried many things but still not successful.
