Variational Product on Amazon provides ASINs for a Parent product as well as for each Child product. However, only Child Products can be imported as 3rd Party items via Amazon API. Parent Product will not be imported.
There are two ways of managing Amazon variational products after they were imported as 3rd party items:
- map each Child product to existing Simple products in Magento, move to M2E Pro listing and continue managing each Child product separately under existing ASINs.
- continue managing product as a Variational product with existing ASIN via M2E Pro. For that, you need to create an identical Variational product in Magento as you have on Amazon (same number of options, SKUs, titles, etc), add it to M2E Pro listing and list it under existing ASIN (the same you have on the channel) using this instruction.
