Enhancement FEDI0001, EXIT_SAPLIEDI_002

I have inherited an already established and activated enhancement to FEDI0001 (Function Exits for EDI in FI), component EXIT_SAPLIEDI_002. I would like to trigger the include within the component, so I can debug to understand and then update the code.

Can you provide the transactions that I need to be perform to trigger this component (inside the include)?

I have set a breakpoint within the include if that matters, but can't seem to get the breakpoint to hit.

Thanks!
