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 InventoryLab.

If you enter a Parent ASIN in the search field, you'll get an alert, informing you that the item is a product with multiple variations.

The Variations will be displayed on the right side of your screen.

Scroll through the list and find the correct variation that matches your item, and then click Use Selected Variation.

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 InventoryLab. If you're not familiar with this process, please check out the links below from Seller Central for guidance:
