MRP Exceptions list with details

Question

Hi gurus,
I would like to know if somebody has a list of most important MRP exceptions with details.
I explain after MRP run, I go in MD06 transaction to display MRP material list. When I display this list I have exceptions and I don't understand all of these exceptions.
Does somebody have a list of principle exceptions with explanations and details or a link to find such a list?
Thank you in advance.
