A generation set is an object that contains the name, code name, and location for an entire site or other set of generated pages.
A generation object allows users to organize data within a generation set. For example, the "Mega Times" generation set could include three generation objects named "Master page", "Variable content", and "TME data".
You must configure a generation set and at least one generation object for distinct page type that you wish to generate in WCM (for example, home page, section page, article page, poll page, collection page).
