In order to import the Distribution Centers (DC) for your ChannelAdvisor orders, all you need to do is create a tag in ShipStation for the same value as your ChannelAdvisor DC code.
For example, if you have a distribution center in ChannelAdvisor titled "Dallas", add a tag in ShipStation called "Dallas".
If you'd like more information on how to create an order tag, please see this article.
After you've added a tag in ShipStation for each of your distribution centers, ShipStation will automatically assign the appropriate distribution center tag.
NOTE: By default, ShipStation will only import orders if all the products have the same distribution center. This is built into our system to prevent duplicate shipments which could be caused by ChannelAdvisor's Fulfillment by Amazon integration, or shipments created by other 3rd party fulfillment houses.
If you need to import all orders, even those which belong to multiple distribution centers, please initiate a chat or open a case with our support team and we can adjust the store's settings to allow import of all orders.
If the store is set to import all orders, order which contain products with a mixture of different distribution centers will include all distribution centers tags that apply to the order. You can then split the order if it must be shipped from separate locations. For more information on splitting orders, please see this article.
