To target a promotion only for specific products in a Loyalty Program, the correct implementation approach is to Map products to promotion through an out-of-the-box Related List (B). This approach leverages standard Salesforce functionality, allowing administrators to associate specific products with a promotion directly within the promotion's record. This direct mapping ensures clarity and ease of administration, enabling targeted promotional activities that are specific to certain products.
Option A (Create a custom list on the promotion), Option C (Create product attributes in Promotion Setup), and Option D (Add promotion to the lookup field on the product) are not standard Salesforce Loyalty Management functionalities for associating products with promotions and may require custom development or configuration that is more complex and less maintainable than using out-of-the-box related lists.
Salesforce documentation on Loyalty Management would detail the process for setting up and managing promotions, including how to associate promotions with specific products to achieve targeted marketing objectives within the Loyalty Program.
