Accrual Write OFF Incorrect . How to amend?

Oracle EBS 12.2.13

We are trying to write off alot of accruals for year end.

We found an old PO with incorrect WO data.

The Receipt QTYis 595. OCT 23 (Created in R11i) Billed QTY = 1.

In NOV 23 above invoice was reversed and a new one created for QTY 459.

So expected WO amount is 595 less 459.

However the Writeoff created was for 594 which seems to be considering the OCT inv only. 595 less 1.

The Load process was rerun and the accrual reconciliation data now looks complete and contains all the NOV 25 data. But if we re-writeoff the same PO will it adjust for the existing WO of 594 and create a correct overall WO amount of 595 less 459 = 136.
