MB-910 Describe Dynamics 365 Customer Insights Practice Question
A data analyst needs to create a measure in Dynamics 365 Customer Insights - Data that calculates the total revenue per customer from the past 90 days. They have a 'Sales' entity with fields: CustomerID, Revenue, and TransactionDate. Which type of measure should they create?
⚠ Common exam trap
Test-takers frequently confuse 'calculated measure' with 'entity measure' because both involve aggregation, but entity measures require a relationship between entities (e.g., a join), whereas a calculated measure works on a single entity with a filter.

Correct answer & explanation
✓
Calculated measure
A calculated measure in Dynamics 365 Customer Insights - Data is used to perform aggregations (like SUM, COUNT, AVG) over a specified time window, such as the past 90 days, using fields from a single entity. Since the requirement is to sum Revenue per CustomerID filtered by TransactionDate within a rolling 90-day period, a calculated measure is the correct type because it allows defining a measure with a time-based filter and aggregation logic directly on the 'Sales' entity.
