Changing the Aging Date in the report does seem to change the report output, it only prints the current payables. I've tried checking off and on the 'consider aging date' and it doesn't seem to make a difference.
I am missing something?
Make sure that you have the ending posting date set for date of the report that you want. Then make sure that you have checked displayed reconciled transactions.
Also, make sure you check the display customers with zero balance.
