Out of the box ATG eCommerce does not support product bundles.  It does support SKU bundles, i.e. a product can consist of multiple SKU’s.

To support product bundles is pretty simple to implement.

First you create a new type of product for bundles in /atg/commerce/catalog/productCatalog.xml.

<item-descriptor name="product">
 <table name="dcs_product">
  <property name="type" data-type="enumerated" default="regular">
   <attribute name="useCodeForValue" value="false"/>
   <option value="regular" code="0"/>
   <option value="bundle" code="1" />
 </property>
 </table>

Then you define your bundles product to have the new products property. This property is simply a list of products that the bundle contains, e.g. Costco organic cotton polo shirt and Nike athletic shorts.

<item-descriptor name="bundle" super-type="product" sub-type-value="bundle">
 <table name="betweengo_product_bundle" multi-column-name="seq_num"
  type="multi" id-column-names="product_bundle_id">
  <property name="products" column-name="product_id" data-type="list"
   component-item-type="product" display-name="Products" category="Bundle" />
 </table>
</item-descriptor>

A few years ago I did a more advanced version of this implementation which allowed for different numbers of products in one bundle, e.g. two different kinds of shirts and one pair of pants.  I did this using the concept of product links which is similar to SKU links that ATG supports.
