This means we were unable to pull the complete product details with regards to offers for the ASIN from Amazon. It can happen on the List and Prep page after searching for an item to add to a batch among other places within our application.
Some Solutions:
Rebind the account and try again
Search for the ASIN again as this can be just a temporary glitch in the feeds. I've found that by the time the user reports it to us it has usually cleared and the item can be added.
Have the user try adding the item directly into Seller Central into a shipping plan via the Add a Product tool under the Inventory tab to see if any errors occur.
