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

Find more information about the Multi-Variational Products in this article.

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.

In case Magento and Amazon attributes are identical, they will match automatically.

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:

  • Magento Product has fewer attributes than Amazon Product

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.

Magento Product`s variations will be available only in a combination with the selected option of the virtual attribute.

  • Magento Product has more attributes than Amazon Product

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 selected ‘Material’ option.

Once selected, the virtual attribute cannot be changed.

Create new ASIN/ISBN

If no corresponding ASIN/ISBN exists in the Amazon catalog yet, you can create a new ASIN/ISBN for your product. For this, add the Description Policy with the New ASIN/ISBN creation option enabled and indicate the attribute for UPC/EAN

In case the product you sell does not imply UPC/EAN (e.g. handmade, private-label) and you have Amazon approval for listing products without Product Identifiers, use one of the Product ID Override options in the Description Policy.

You can create the Description Policy under Amazon > Configuration > Policies. Read this article for more details.

If you list Magento Variational Product under new ASIN/ISBN, M2E Pro automatically considers you as a creator of ASIN/ISBN. 

Once the Description Policy is set, you need to select a Variation Theme for your item. For this, click Manage Variations next to the necessary product in the Listing grid and switch to the Settings tab. There you can specify Variation Attributes for your product or create Virtual ones if necessary.

As a creator, you can generate an unlimited number of new Child Products for selected Parent Product and add new options of the Variation Attributes for the Parent Product.

As a rule, Amazon strictly regulates the creation of new Attributes for the product. 

If you assign Magento Product to ASIN/ISBN you created outside the M2E Pro, you are not considered its creator by default. For this, you need to click I am the Creator under Amazon > Listings > Manage Variations > Settings. 

Once done, M2E Pro will start the verification process. In the Settings tab, you also need to specify the SKU of the Amazon Parent Product. When SKU is found, M2E Pro marks it as created by you.

Following the above-mentioned steps, you will easily assign your Multi-Variational Products to the appropriate ASIN/ISBN via M2E Pro.
