What product subtype should be chosen for a uniquely identifiable core product?

The product subtype chosen for a uniquely identifiable core product is the product. This is because a core product refers to a standalone product that has its unique characteristics and attributes, making it distinctly identifiable within the system. By defining it as a product, you can manage and track it effectively, including its inventory levels, pricing, and lifecycle.

The distinction lies in how each subtype is utilized within the product hierarchy. A product serves as the foundational element, representing individual items that can be purchased or sold. In contrast, products like product masters and product variants are utilized in scenarios where you have a parent item with various configurations or variations based on certain characteristics (such as color, size, or style). For inventory management or sales scenarios where you need to highlight an item’s unique features, selecting the product subtype is appropriate to ensure clear identification and management of that item throughout its lifecycle.

Choosing "item" would be more generic and does not emphasize the unique characteristics of the core product, which can lead to management difficulties.
