Changing standard print program for Payment Medium Workbench in FBZP

Hi all,

Currently I'm trying to change the standard print program - RFFOAVIS_FPAYM for Payment Medium Workbench in FBZP under Pmnt methods in country, but can't seem to see any option for me to do so.

Can anyone tell me how could I change the standard print program RFFOAVIS_FPAYM  to my own customized program?

Thanks.

Regards,
