Difference in Historical Aging & AP Aging

Hi,

I have a year end aging report that the balance matches to the control AP account. When I ran the Historical Aging Report for the same year end I got a report with a different balance amount. I can see the transaction in the Historical Aging Report that is causing the AP Aging & control AP accounts to be off. My question is, is there a way to remove this transaction from the Historical Aging Report so it matches the Year End Aging report and AP control account? 

Any help would be greatly appreciated!

Thanks,

Bob.
