Our client wants to understand whether they can create a new custom Transaction Source in Oracle Fusion Accounts Receivable and use it for invoices imported from Order Management (OM), instead of continuing with the standard Distributed Order Orchestration (DOO) transaction source.
They would like to know:

1. Is it possible to replace the seeded “Distributed Order Orchestration” transaction source with a custom one for the OM-to-AR invoice import process?
   
2. If yes, what steps are involved in replacing DOO with a custom transaction source?
   
3. What are the key considerations, potential impacts, advantages, and disadvantages of using a custom source instead of the standard DOO source?
