I don't understand the question.  What are you looking for?  

You can run a trial balance but it will be for all of the accounts being used in Sage 50.   You can also run AR and AP Reports.

I know not what I know not.  Lol.  When running the Internal Accounting Review before changing the last period, we discovered that our A/R is out of balance.  I called our CPA to ask for advice on how to track down the discrepancy, and he said to run a trial balance for the A/R.  Did he just mean to run the GL trial balance and look at the A/R account balance on that report?
