CM20200 table contains transaction detail
CM20300 table contains receipt transaction detail
CM20500 contains Statement Balance, any adjustment amounts
CM00100 contains all the checkbook ID, the balances and other data
So, there is no one answer to your question. Using Smartlist Builder or Designer ( depending on what you have installed ) will be the best way to combine the data from the two or three tables in order to answer the question as well as get the actual report.
If you want to know who did the Reconcile for Oct 1 - batch ID - OCT2016 then you can find that in the CM20500 but as soon as you also want to know the rest of these details, you have to start combining other tables.
Hope this helps.
