A data requirement to support successful creation of the Tableau CRM app for Consumer Goods Cloud is that products must be associated to retail stores. This is because the Tableau CRM app analyzes the sales performance and product distribution across different stores and segments, and identifies opportunities and gaps for product placement and availability. Without associating products to retail stores, the app cannot provide accurate and meaningful insights. Verified Reference: [Salesforce Consumer Goods Cloud Implementation Guide], page 37.

A promotion check is a type of action plan task that allows a field rep to verify if a promotion is running correctly at a retail store. When executing a promotion check in the field, two standard capabilities are available: viewing which products are included in the promotion and taking a photo of the promotion. These capabilities help to ensure compliance and capture evidence of promotional execution. Verified Reference: [Salesforce Consumer Goods Cloud Implementation Guide], page 27-28.

Two primary use cases for performing an in-store survey are:
Gathering feedback from customers, consumers, shoppers, and staff. An in-store survey can be used to collect feedback from various stakeholders who interact with the products or services offered by the consumer goods company. For example, an in-store survey can ask customers about their satisfaction, preferences, or suggestions; consumers about their awareness, perception, or loyalty; shoppers about their behavior, motivation, or barriers; and staff about their challenges, needs, or opinions.
Gathering data on promotions, inventory requirements and product quality. An in-store survey can be used to collect data on various aspects of the product performance and availability in the retail store. For example, an in-store survey can ask about the compliance, effectiveness, or impact of promotions; the demand, supply, or replenishment of inventory; and the condition, quality, or issues of products

Promotion Product, Promotion Channel, Retail Store KPI, and Retail Visit KPI are four objects that have promotions associated with them using the Consumer Goods Cloud Data Model. These objects help users to define, execute, and measure promotions in retail stores. They are:
Promotion Product, which represents a product that is part of a promotion.
Promotion Channel, which represents a channel or segment where a promotion is applicable.
Retail Store KPI, which represents a key performance indicator that measures how well a retail store is performing against a specific promotion goal or target.
Retail Visit KPI, which represents a key performance indicator that measures how well a field rep executed a promotion during a store visit. Verified Reference: [Salesforce Consumer Goods Cloud Implementation Guide], page 30-31.
