Similar to Simple Products, you can assign the existing ASIN/ISBN or create a new ASIN/ISBN for Multi-Variational Items using M2E Pro.

Assign existing ASIN/ISBN

When you list Multi-Variational Item via M2E Pro, Magento Parent Product is matched with existing products in the Amazon catalog and, is assigned to the appropriate ASIN/ISBN. You need to match Magento and Amazon attributes in order to locate ASIN/ISBN for the product.

<aside> ✅ In case Magento and Amazon attributes are identical, they will match automatically. If you want to edit matched Attributes, click Manage Variations next to the Product in the grid.

<aside> ⚠️ Please remember that Parent Product is not added to your Amazon Inventory if you list Magento Variational Product under existing ASIN/ISBN.

You also need to ensure the number of attribute values is the same for Magento and Amazon Products. If it is different, you can create a virtual attribute so M2E Pro displays your product correctly on the Channel. Find several examples below:

Let`s say your Magento Product varies by attribute ‘Color’, whereas the corresponding Amazon Product contains two variational attributes — ‘Color’ and ‘Size’.

In this case, you need to select the value that does not exist in the Magento Product (‘Size’). M2E Pro will virtualize the ‘Size’ attribute. On Amazon, this product will be available with the attribute ‘Color’ and the selected ‘Size’ option.

<aside> ⚠️ Magento Product`s variations will be available only in combination with the selected option of the virtual attribute.

</aside>

Let`s say your Magento Product varies by attributes ‘Color’, ‘Size’, and ‘Material’ whereas the corresponding Amazon Product contains only two variational attributes — ‘Color’ and ‘Size’.

In this case, you need to select the value that does not exist in the Amazon Product (‘Material’). M2E Pro will virtualize the ‘Material’ attribute. On Amazon, this product will be available with attributes: ‘Color’, ‘Size’, and the selected ‘Material’ option*.*

<aside> ⚠️ Once selected, the virtual attribute cannot be changed.

When Attributes are matched, M2E Pro will begin creating Child Products based on the matching of Options. M2E Pro automatically matches Magento Variations with Amazon Variations and creates Child Products.
