You tell me what you are doing, what your settings are and how you are running the process to get the message, then I will comment on it.
You tell me what business scenario you are trying to match, then I will tell you how I would process it.
Otherwise I could be giving you examples until the end of time and none of them will mean anything to you.
Additionally try setting the system up and running the plan with different settings and seeing the differences between plans - doing it yourself is the simplest and most effective way to learn.
