Hi,
Please read standard AX Development manuals (available in PartnerSource / CustomerSource) which explains in high level each process in technical terms.
Secondly this was discussed many times here. Please do search for them.
Lastly sorry to be blunt - but if you want to understand nitty-gritties (which is what your query is), you will have to debug and understand this yourself. This is not very difficult!
