Can you cancel an accrual write off?

Is it possible to cancel or reverse AP PO Accrual Write Offs that have already been performed?

Having run the accrual reconciliation load run I processed a number of accrual write offs based on certain parameters, namely age and value. It would appear that a number of transactions which should not have been written off were selected and written off. For example, a Purchase order with a single line item and a single receipt is fully matched and paid. There are numerous examples of this in the batch of write-offs performed.

I am seeking to establish if there is any process where all of these write offs can be reversed or cancelled and the relevant sub-ledger accounts returned to their original state?
