Error:

- [Code:8005] [Error] You are attempting to change an identity attribute for this SKU. To proceed, please delete this SKU and recreate the SKU with the appropriate identity attribute. For more information and detailed instructions, see: http://sellercentral.amazon.com/gp/help/23191



Explanation:

Typically this error would be triggered when the product details do not match the details, that Amazon have for that particular product in their catalog. Amazon would accept it like you are trying to list the item to the incorrect ASIN and quite often one of the things, that could trigger it is if the UPC, that was pushed to the channel would not correspond to the actual UPC, which is already tied to the particular ASIN.
