Overview

The Reduce Inventory step decreases the actual inventory count for shipped order lines. It processes only released shipments and tracks inventory transactions to prevent duplicate reductions.

Configuration Properties

This step has no configurable properties.

Behavior

What It Does

1. Identifies shipments with Released status
2. If running at shipment level, only processes the current shipment
3. Generates internal references for tracking (OrderId + ShipmentId + LineItemId)
4. Checks existing inventory transactions to prevent duplicate reductions
5. For each non-virtual product line item:
   • Calculates quantity (quantity minus canceled quantity)
   • Decreases 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
6. Returns warning if inventory was already reduced

Prerequisites

• Shipments must be in Released status
• Line items must not be virtual products
• Inventory transaction tracking prevents duplicates

Side Effects

• Actual inventory count decreases
• Creates inventory transaction record
• Updates line item Cost and CostTotal fields
• Currency conversion applied if needed

Business Cases

When to Use

• Order fulfillment: When goods physically leave the warehouse
• Ship status transition: Standard step when moving to Ship status
• ReadyForPickup: When click-and-collect items are prepared

Example Scenarios

Scenario 1: Standard Shipment Order with 5 items ships. Step reduces inventory for all 5 items in the warehouse and updates costs.

Scenario 2: Partial Shipment Order has 2 shipments, first ships. Running at shipment level reduces inventory only for that shipment's items.

Scenario 3: Already Processed Workflow runs twice accidentally. Step detects existing inventory transaction and returns warning without duplicating.

Scenario 4: Cost Update Inventory item has cost recorded. Step retrieves cost, converts from USD to EUR (order currency), updates line item.
