Requirement to link legacy Sales order and Purchase order and create reservation via FBDI

Hello,

We have a requirement to link the legacy Sales orders and Purchase orders for B2B items and create reservations for those Sales orders through reservations FBDI load. We will be loading the Sales orders and Purchase orders through FBDI into Oracle Fusion.

Seeking your suggestions to understand if there is any way to achieve linking the legacy sales orders and purchase orders and create reservations via FBDI. Thanks in advance.
