All the AP Batches were posted and retrieved into the GL at the time. This happened several months ago and I did not check the AP ledger balance to the subledger until now (our year end is January 31st, so I am in the beginning stages of review).

The invoices were dated prior either by accident (key punch errors) or were actually prior to January 31, 2008. At January 31, 2008, all was okay, the subledger matched the gl. With the new version Adagio 9, the AP person didn't get any error messages after the year end finished when she entered these invoices.
