Ship Replacement in Parts Replacement
The depot repair shipment process is different from parts only shipments because the part to be shipped doesn't exist in inventory when creating the shipment sales order line.
Add the Asset Management step and remove the Schedule and Create Reservation steps. You must add the Asset Management step to update the installed base when shipping the repaired part back to the customer.
I have added Orchestration step of Asset, TaskType as "DOO_AssetManagement" in the end of Ship Line Orchestration process the Ship line always goes to Awaiting Shipping .
