Hiding standard fields through Get_Data method of CL_EHFND_FBI_GUIBB_FORM

Hi Experts,

I want to hide the standard fields from FPM form screen, for that screen generic feeder class CL_EHFND_FBI_GUIBB_FORM is being used.

can you please suggest me where should i add my custom code for hiding or disabling some of the standard fields?

I think this feeder class is very generic in nature(must be called from within many FORM UIBB) so writting custom code in POST EXIT of GET_DATA method of this generic class should not be the right approach.

kindly suggest.

Regards,
