If you have a product with a variation, such as Apparel or Shoes, you will need to locate the correct Child ASIN for that product when adding it to a batch in Stratify.
If you submit a Parent ASIN in the search field, a Select Variation button will appear.
Click Select Variations to bring up a list of the existing Child ASINs to choose from.
After scrolling through the list and finding the correct variation that matches your item, click Select this Variation next to it.
This will bring you to the Item Listing Details page and allow you to list the item with the correct Child ASIN for your variation.
If you cannot find the Child ASIN for your variation, you will need to create the variation in Seller Central before it can be used to list in Stratify. If you're not familiar with this process, please check out the links below from Seller Central for guidance:
