The following factors might be the reason why the inventory of products within an FBA shipment is not being deducted.
- Check on the settings page at “locations” if the default sock location is set for the warehouse where you want the inventory should be deducted by default. Click Here for an article explaining the default stock location.
- If a different “ship from warehouse” was selected on this shipment, the inventory will be deducted from that location.
You may also check on the activities of the products within the shipment to see if the inventory was added to that store.
