Member Engagement Attributes are designed to track and aggregate a member's activities and behaviors over a specified period. They are used to determine a member's eligibility for a promotion based on cumulative actions rather than a single event.

Scenario A requires tracking the total transaction amount each month for a year. Scenario B requires counting the number of training attendances within a specific two-month period. Both scenarios involve tracking member behavior over time, which is the primary function of Member Engagement Attributes.

C. Member buys apparel online and gets 400 bonus points if the member belongs to Gold Tier only.

This is a standard transactional promotion. Eligibility is based on a single transaction and a static member attribute (tier), not on cumulative behavior tracked over time.

D. Member enrolls in “welcome aboard” promotion for free surprise gift every quarter.

This scenario's eligibility is based on the act of enrolling in a promotion, not on tracking specific member activities or behaviors that would require an engagement attribute.

1. Salesforce Help, Loyalty Management, "Track Member Behavior with Member Engagement Attributes":

This document states, "Member engagement attributes help you track your members’ activities and behavior for a specified period. You can use these attributes to determine a member’s eligibility for a promotion." It provides examples like tracking the total transaction amount in the last 30 days or the number of times a member has used a voucher, which directly aligns with scenarios A and B.

2. Salesforce Help, Loyalty Management, "Promotions":

The overview of promotions explains how rules can be configured to trigger on specific events like transactions. For scenario C, a standard promotion rule would be created to check the product type (apparel) and the member's tier (Gold) within a single transaction journal, without needing to track cumulative data.

3. Salesforce Help, Loyalty Management, "Create a Promotion":

Under the section "Define Eligibility for the Promotion," the documentation distinguishes between standard eligibility (like tier or enrollment) and eligibility based on engagement attributes. This distinction clarifies why scenarios C and D do not require engagement attributes, as their eligibility can be defined through other standard promotion settings.
