Question:

I need to modify the data and the layout of transaction F.62 (Print Journal Voucher).  I have searched information from the web that it is possible to add a custom print program to modify the logic.  I would like to ask what is the transaction code in FI for configuring this Tcode F.62 to use this customize print program. (Like NACE for SD and MM modules).
