Approach to write-off migrated AP Invoices

Hi Team,

Considering the scenario where in from an operating unit in AP (Oracle EBS R12 v12.2.4), business migrates 50% of the invoices belonging to certain category to target ERP. And, continue to use Oracle EBS R12 AP module for rest of the non-migrated invoices.

To avoid duplicate processing of migrated AP Invoices, what should be write-off approach in Accounts Payable for migrated AP Invoices.

Thanks
