Explanation:
A product in the API Management capability within SAP Integration Suite is a bundle of one or more API proxies that are grouped together for a specific business scenario or use case. A product is a separate artifact that can be deployed to the API business hub enterprise, which is a centralized platform for discovering, consuming, and managing APIs. A product can have its own metadata, such as name, title, description, quota limits, and so on. A product can also have its own policies that apply to all the APIs included in it.
