In Salesforce Consumer Goods Cloud, a promotion is fundamentally defined by the products it applies to. The platform allows for this definition at two distinct levels of product granularity. A promotion can be associated with one or more specific, individual products. Alternatively, for broader campaigns, a promotion can be linked to an entire product category, which automatically includes all products within that category. These associations are managed through the Promotion Product and Promotion Product Category junction objects, respectively, which link to the primary Promotion record.

A. Account: An Account represents a customer or channel where a promotion is executed, not a level at which the promoted products are defined.

C. Retail Store Group: A Retail Store Group is a target channel for a promotion, specifying where it runs, not what products are on offer.

E. Retail Store: A Retail Store is a specific location for promotion execution, typically targeted via its parent Account or Retail Store Group.

1. Salesforce Help, Consumer Goods Cloud, "Promotions in Consumer Goods Cloud": This document explicitly states, "A promotion is a campaign that you run for a specific period to increase the sales of specific products. You can create a promotion for a product or a product category." This directly confirms that promotions are defined at the Product and Product Category levels.

2. Salesforce Help, Consumer Goods Cloud, "Promotion Management Data Model": The official data model diagram for Promotion Management shows the Promotion object having direct relationships with the Promotion Product and Promotion Product Category objects. This illustrates that the core definition of a promotion's scope is tied to these two levels.

3. Salesforce Help, Consumer Goods Cloud, "Create a Promotion": The procedural steps for creating a promotion detail adding products to the "Promotion Products" related list or categories to the "Promotion Product Categories" related list, reinforcing these two as the primary definition levels.
