Best Practice & Recommendation to convert Open SalesOrder for B2B (Buy/Make/Transfer) & DropShip sce

Summary:

We have requirement for converting open sales orders into Oracle Fusion Order Management that include both drop ship and back-to-back items (which could be Buy/Make/Transfer)

Observation: The system creates requisitions and new POs for the B2B Buy items, works orders for B2B Make items and similarly for the other scenarios. However, in the legacy system, customers may have already issued POs to suppliers, Work orders in progress or transfer orders partially received and so on and so forth.

Ask : What’s the best practice for managing the conversion for Sales Order considering there could be legacy system-generated supply documents or not generated; also some could be partially completed as well.
