What It Does

1. Identifies shipments with Released status
2. Generates internal references for tracking (OrderId + ShipmentId + LineItemId)
3. Checks existing inventory transactions to prevent duplicate reductions
4. For each non-virtual product line item:
   • Calculates quantity (quantity minus canceled quantity)
   • Decreases both actual inventory and reserved inventory at the specified warehouse and virtual warehouse
   • Updates line item cost from inventory if available
   • Converts cost to order currency if different from default
5. Returns warning if inventory was already reduced for the order

• Complete order: When marking orders as completed

Example Scenarios

Scenario 1: Standard Order Ship Order reserved 10 items. When shipped, step reduces both actual inventory and reserved inventory by 10.

Scenario 2: With Cost Tracking Items have cost data in inventory. Step updates line item costs during reduction, enabling margin reporting.
