Reconciling AP Batches

What is the difference between these two AP processes, Payables Accounting Process Report" and the "Transfer to the General Ledger?  

Also, what is a good way to reconcile the AP batch posting to GL from an AP and a GL side?  I'm being asked to do a reconciliation of the two.  Currently, I take the batch posting I get from our AP Supervisor from the Transfer to the GL totals and compare those to the GL posting entry. 

Thanks
