After each upload of an offer file, you can download a report file from your Seller Office. You can find the file and report it under the Manage Offers tab.

This report file provides detailed information on whether your offer data was sufficient. Lines with warnings can be edited and we can create or update the offer. 

Warnings should be corrected if you choose to include the information in your listings. Incorrect lines will not be processed and the offer will not be created or updated. Once all errors are corrected, you may upload the offer again.
