What does the posting error “Item has no valid shipping rates configured” mean?
This posting error is an internal error that ChannelAdvisor gives when a listing is attempted to be posted for an item that has no valid shipping rates setup within a ChannelAdvisor posting account. In order to post an item, you will need to include some type of shipping rates for your items. The easiest way to set up shipping is to include a Global Level rate on the Sales > Shipping > Account Shipping Rates page. The rates on this page will affect all inventory items in your account unless they are already setup with either a class or item level shipping rate.
