MISSING_DIMENSIONS

This error generally occurs with new listings or listings that were previously merchant fulfilled and Amazon does not have Item and package dimensions to assign the item a fulfillment center.

Solution- Search the listing in your Seller Central inventory. Edit the listing by adding item and package dimensions to the listing.

You can edit a listing on seller central in the inventory tab under "Manage inventory". Press edit next to the listing that is missing dimensions to access the edit listing page.

Once the edit listing page is opened you can find the place to input item and package dimensions under the shipping tab.

Make sure to enter the dimensions and weight for each field. Amazon also asks for the unit of the dimensions input ( Inches, Centimeters). If any field is not filled in Amazon will not be able to generate a shipment plan for the item.

Once amazon has the items dimensions, view the shipment and press the sync button next to the item.

You can confirm that Amazon has the item dimensions by searching the Asin on the FBA revenue calculator.
