Reduce the utilization of your restock limits by decreasing your FBA inventory or cancelling open shipments for items you don’t plan to send to Amazon. Open shipments can be viewed and canceled from the Shipping Queue.
To decrease inventory in a fulfillment center, you have two main options: sell more or create a removal order. If you opt to create a removal order, you can have your inventory returned to you or have Amazon dispose of it.
After submitting a removal order, your inventory storage volume won’t show the changes until the request has been processed.
