Amazon has data fields that are named the same in all sales channels (e.g. Amazon.de, Amazon.fr), but whose values differ depending on the country. 

When creating a Channel map for Amazon in the Data » Catalogues » Tab: Channel maps menu, you can now select a country-specific sales channel for Amazon (e.g. Amazon - Germany, Amazon - France) in the Marketplace field. This ensures that country-specific values in the data fields are correctly mapped and transmitted.
