Behavior

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:
   • Checks if ReservedInventoryQuantity > 0 to determine if item was reserved
   • Calculates quantity (quantity minus canceled quantity)
   • If reserved: Calls ReduceInventoryAndReservedInventory()
   • If not reserved: Calls ReduceInventory() only
   • Updates line item cost from inventory
   • Applies currency conversion if needed
5. Returns warning if inventory was already reduced

Prerequisites

• Shipments must be in Released status
• Line items must not be virtual products
• Line items have ReservedInventoryQuantity set during reservation

Side Effects

• Actual inventory always decreases
• Reserved inventory only decreases for reserved items
• Creates inventory transaction record
• Updates line item Cost and CostTotal fields

Business Cases

When to Use

• Mixed reservation workflows: Some items reserved, others not
• Dropship/transfer orders: Items received without prior reservation
• Manual order entry: When reservation was skipped
• POS orders: Often bypass reservation

Example Scenarios

Scenario 1: Mixed Order Order has 5 items: 3 were reserved, 2 were added later without reservation. Step reduces inventory for all 5, but only reduces reserved inventory for the 3 reserved items.

Scenario 2: POS Integration POS order imported directly. Items were never reserved. Step reduces inventory without touching reserved counts.

Scenario 3: Backorder Fulfillment Items arrived from purchase order and added to order without reservation. Step handles them correctly.
