SAP Personas - How to call flavor in SAP Personas from ABAP program

Hi

We have created the flavor for ME23N in SAP Personas V2.0 and in our MM report in the backend, we have the hotspot click on the PO number to call transaction code ME23N to display that PO.

We want to make the hotspot click on the PO number and link to our flavor of ME23N in Personas and display that PO.

We have able to link to the flavor of ME23N in Personas but it is not display the PO number that we click.

The below is the sample code:

SET PARAMETERS ID 'BES" FIELD p_pono.

CALL METHOD cl_gui_frontend_services=>execute

  exporting

   document = 'http://................................/sap/bc/bsp/persos/mainapp/index.html?link= E50A.........'

  exceptions

   others = 1.

Does anyone know how to make it work?

Regards
