Hi everyone,
I was aware of the fact that Cases and Event_log tables are required, but thought there is a way to replace them with other tables, especially after studying the Oracle P2P App template - obviously, the difference is how the Oracle P2P App template was designed in the backend. Thus, I will merge all events in the Event_log.
Thank you very much all for your prompt responses and clarifications!
Also, good to know about the upcoming update on the multi eventlogs - thanks Martijn and Ankit!
