Sap Personas & RFC

Hi Guys,

I'm trying to get a simple data into my Personas textfield using RFC.

Same as showen in the link below:

How to use RFCs in Personas 3.0 - SAP Imagineering - SCN Wiki

var rfc = session.createRFC("BAPI_USER_GET_DETAIL", "");

     rfc.setParameter("USERNAME", "XXXXXX");

     rfc.requestResults(JSON.stringify(["ADDRESS", "RETURN"]));

     rfc.send();

var address = JSON.parse(rfc.getResult("ADDRESS"));

     session.utils.log(address.FULLNAME);

I'm getting an error when excuting my script

In Scripting editor session.createRFC is not found in the list of session.(objetcs)

Error during script execution:

TypeError: undefined is not a function

at eval (eval at <anonymous>

Can any one help me ?

Many thanks,

Medix
