By default, Inventory included on a sales order is reduced from the highest priority warehouse with available quantity. Click here for more information on warehouse priority order. If a situation arises where you would like to fulfill an order from a different warehouse, you can manually change the warehouse assignment using the process outlined below:
1. Locate the Order by navigating to Orders > Order Management > Paid - Ready to Ship
2. Click Actions> View
3. Click the Green '+' Icon next to an item. Use the Warehouse dropdown to specify the warehouse you would like to fulfill the item from
4. Click Actions > 'Save'. The Inventory will now be reduced from the new warehouse. If this order needs to be exported, the items will be exported to the new warehouse assignment.
Note: Warehouse Overrides are item specific, so different products can be assigned to different warehouses using this process.
