To edit a Pending Upload, simply double click on the Pending Uploads tool in the Inventory Management section. A screen similar to the one below will appear. If the item you are editing is an existing listing, some of the fields such as SKU and condition cannot be edited. Once you are happy with the changes, you may click on Modify to cause the change to take place immediately or click on Save to save your changes in Pending Uploads and move to the next item. Saved changes may then be uploaded using  the steps in Upload Inventory to Amazon.
