Why does Amazon need the dimensions of a product?
Amazon needs dimensions for all products in its catalog to ensure it’s compliant with safety and hazmat regulations, ensure size for proper FBA warehouse routing and customer satisfaction.
If your item is getting kicked back because it is missing dimensions then that means Amazon doesn’t have them on file for that ASIN (or product). This is most likely due to that ASIN only ever being sold on the Amazon marketplace as Merchant Fulfilled or when the original listing was created the seller never entered the dimensions.
Remember, most of the stuff sold on Amazon is coming from 3rd parties and whoever creates the listing first is responsible for entering all the data about the product.
Amazon is just the marketplace for which these items sell on.

This is an error related to missing dimensions for a particular product. As stated above, this means dimensions weren't added for this product, and if at all they were, the data somehow isn't accessible by Amazon API..
For Entering Missing Dimensions in AccelerList, you will be essentially adding the product to your inventory in Seller Central the old fashion way and saving the correct dimensions as you do this.Once this has been done, the dimensions will be saved for that product in the Amazon catalog and you can now list it in AccelerList.
Option 1:
1. Add the MSKU to a shipment plan in Seller Central. This is done by either adding the product to your inventory or locating it and using the send/replenish action
2. Amazon will prompt for dimensions. Enter the dimensions.
3. Return to AccelerList and list the item as normal.
4. After the shipments have been created, it is safe to delete the shipping plan entry. You should not delete the shipment plan or shipment plan entry until the shipments are created in Seller Central.

Once the item is saved, in Seller Central, click on Inventory and select Manage Inventory from the dropdown box
