The childSKUs property of a product is a list of all the SKUs that are children of the product. A product called Apples might have several different SKUs that represent different varieties of apples, such as McIntosh, Delicious, and Granny Smith.
The product item also has a property named displayableSkuAttributes, which you can use to specify a list of the SKU properties that can be displayed using the DisplaySkuProperties servlet bean. For more information about this servlet bean, see the Displaying SKUs section of the Catalog Navigation and Searching chapter of the ATG Commerce Guide to Setting Up a Store.
