Explanation: To monitor members' tier history in the dashboards from the Analytics Studio App, the two fields that need to be enabled in field history tracking on the Loyalty Member Tier object are:
Change Reason Type (B): This field captures the type of change (e.g., manual adjustment, system-generated change) that led to the tier change, providing context for the tier history.
Reason for Change (D): This field provides specific reasons for the tier change, offering detailed insights into why a member's tier was adjusted, which is valuable information for analyzing member behavior and program effectiveness.
Option A (Loyalty Tier Group) and Option C (Loyalty Tier) are important fields for understanding tier structures and member status, but they do not specifically relate to tracking changes or the reasons behind tier history, which are crucial for analytical purposes.
Salesforce documentation on Loyalty Management and Analytics would provide guidance on configuring field history tracking and leveraging Analytics Studio to create insightful dashboards that monitor and analyze members' tier history, aiding in strategic decision making and program optimization.
