Products vs Product Groups

The PSS Catalog Team groups products with different attributes together so that they can display on a marketplace with drop downs or attribute selectors.

A Product is an MPN.  There is only one MPN per product.

A Product Group is all the different variations of a single product.  There are multiple MPNs in a Product Group.

In the below example we will look at a Product Group of Axcalibar Pro Axles by Lone Star Racing.  

Filter the Catalog by Lone Star Racing and click on the Product Name for one of the lines.  This will bring up the entire Group.  Notice how each MPN has a different attribute.
