Hi,
the new fields -
in your PBO you should be using the method /scwm/cl_rf_bll_srvc=>set_screen_param and if it is a table then transfer to the RF framework by method /scwm/cl_rf_bll_srvc=>set_scr_tabname.
The application parameter must be customized and be part of the FM interface as changing parameter.
Is this everything you already did?
Thanks.
Petr
