Orchestration for a ATO model, where fulfillment lines are routed to different external systems

Summary:

Need help in setting up the orchestration for a ATO model, where fulfillment lines are routed to different external systems

Background: We have requirement to route certain order fulfillment lines to an external system via OIC outbound integration, while another inbound integration allows the flow of status updates from the external system to fusion.

Our requirement is to update these status update, only on that fulfillment line in sequence of Status B > Status C, and exit the orchestration step at Status C.

Issue:

We have a ATO model item on the sales order line, of which only one option item’s fulfillment line is eligible to route to the external system for fulfillment. The Orchestration number is same on all the fulfillment lines.
