Hi,
The steps to create a copy of an an application class is as follows:
1. Create Client-Independent Application Class(BRFAPL01).
2. Copy Implementing Classes(FKKBRFCIMP) -- you are missing this!
3. Copy Application Class(FMCABRFTRANS).
Probably you need the implementing class also for additional functionality.
I hope this will solve your query.
Also, for more details you can refer the below link:
