Q. What is an "Ancestor Portfolio"?

A. In CET catalogs, the concept of ancestor portfolios allows one portfolio to act as a parent to other portfolios. This setup is useful when multiple portfolios need access to the same materials. Instead of copying the same assets into each portfolio, manufacturers can create a parent portfolio that contains the shared materials. Then, the child portfolios can access those materials directly.

This approach helps avoid duplication and is commonly used. Additionally, a parent portfolio can also have its own parent, creating a chain of portfolio relationships.
