Amazon Shipping Templates for Merchant Shipping Groups:
First, you'll need to get the shipping templates setup in Amazon. Then you'll need to give us the latest flat files of the category you are posting to because some of the old versions don't allow us to post to the shipping template. If your flat file already has this there is no need to send us an updated flat file.
You'll need to setup a custom field in NetSuite that will contain the name of the shipping template and we will need to map that for you, so please let us know the field id once you've set this up.
