I had been printing the Aged Trial Balance using version 8.1A. I then tried printing the same report changing the report option from "aged as of" to "calculate as of" and my totals are still not correct for 2009. I know for a fact that one customer owed a certain amount at December 31, 20009. He isn't showing up on the report regardless of which print specification I use.

When I run the report for 2010 all of my manually calculated receivable balances match with the subledger.

I'm confused at to why the 2009 totals aren't accurate but the 2010 totals are.
