On this step, the correspondence between Magento and Walmart Attributes must be set. The attributes will be matched automatically if your product varies by a single variational option. Otherwise, you will need to associate the attributes manually. 
| Note |
|---|
| Matching of Variational Attributes is required. Otherwise, the product cannot be listed on the Channel. |
| Note |

| If you change the Variational Attribute or Variational Option names in MagnetoMagento, you will have to match Magento Variational Attribute(s) with Walmart Variant Attribute(s) again. |
After the Attributes are matched, M2E Pro will automatically create Walmart Item Variations based on your Magento Product Variations. Switch to the Child Products tab to review the product variations:

| If you have different Websites created in your Magento, make sure that Magento Child Products are checked in the Website relevant to your M2E Pro Listing. Otherwise, the product variations will not be displayed under the Child Products tab. |
