Order Consolidation helps reduce split shipments by first checking whether the items in an order can ship from one warehouse.
When enabled, Luminous will try to fulfill eligible items from a single warehouse before splitting them across multiple warehouses. This is especially helpful when a customer would prefer fewer shipments, even if that means using a lower-priority warehouse that can fulfill everything together.
How Luminous Chooses Which Priority List to Use
Before Luminous decides which warehouse should fulfill an item, it first determines which fulfillment priority list applies to that item.
Luminous checks in this order:
- A priority list set directly on the line item
- A priority list set on the order
- A priority list set on the product
- The default fulfillment priority list
The first match is used.
How Order Consolidation Is Applied
Once each line item has a priority list, Luminous groups together items that use the same priority list.
Then, for each group, Luminous asks:
“Can one warehouse in this priority list fulfill all of these items?”
If yes, Luminous creates one fulfillment order from that warehouse.
If no, Luminous falls back to the normal routing behavior and may split the items across multiple warehouses based on the priority list and available inventory.
Example 1: All Items Use the Default Priority List
An order has three items:
- Backpack
- Wallet
- Packing cube
All three use the default priority list:
- Warehouse A
- Warehouse B
- Warehouse C
Warehouse A has only the backpack. Warehouse B has all three items.
With Order Consolidation enabled, Luminous will choose Warehouse B because it can fulfill the full group from one warehouse.
Without Order Consolidation, Luminous may choose Warehouse A for the backpack and another warehouse for the remaining items, creating a split shipment.
Example 2: One Product Has Its Own Priority List
An order has three items:
- Backpack
- Wallet
- Special accessory
The backpack and wallet use the default priority list.
The special accessory has a product-specific priority list.
Luminous will treat these as two routing groups:
- Group 1: Backpack and wallet using the default priority list
- Group 2: Special accessory using its product-specific priority list
Order Consolidation will try to consolidate each group separately. It will not ignore the special accessory’s product-specific priority list just to force the whole order into one warehouse.
Example 3: One Line Item Has a Specific Priority List
An order has three items:
- Backpack
- Wallet
- Replacement part
The replacement part has a priority list set directly on that line item.
That line-level setting takes priority over the product, order, and default settings.
Luminous will keep that item in its own routing group if its priority list is different from the rest of the order. Order Consolidation will not override that line-level rule.
Important Note About Order-Level Priority Lists
If a priority list is set on the order itself, it applies to items on that order unless a specific line item has its own priority list.
That means an order-level priority list can override a product’s normal priority list.
Summary
Order Consolidation does not mean “force the entire order into one warehouse no matter what.”
It means:
First, Luminous determines the correct priority list for each item. Then it groups items that use the same priority list. Within each group, it tries to fulfill everything from one warehouse before splitting.
