Unable to Delete Write Off

If you are unable to delete a Write Off because it has already been through a Billing Cycle, go to AR Manager and call up the WO transaction in the AR Entry window.  You may also go to Action > Payment Application Posting, and locate and double click on the transaction.  Once the transaction is displayed in the AR Entry window, choose TOOLS, Reset Invoice Status to Selected.  If you then want to delete the WO transaction, you will first have to close AR Entry and then call back up the WO transaction and delete it.
