Before starting to push products you need to import some data from Wynshop into the PIM: Categories and Stores.
Important: You need to import the categories first then the stores so that the system will assign the right category tree to the store.
1- Category Trees Import
In the Wynshop channel configuration page, go to the Import tab and click on Import Wynshop Categories. This action will import all category trees from Wynshop into the PIM.
2- Stores Import
In the same tab, click on the Import Wynshop Stores. This action will import all stores from Wynshop and create a channel in the PIM for each store. It will also assign the category tree previously imported to the store.
