What is one primary benefit of using a rollup field?

Using a rollup field provides a significant advantage by offering calculated values across related records. This feature is particularly valuable when dealing with entities in Microsoft Dataverse where you want to aggregate data from child records.

For instance, if you have a parent entity like "Account" and related child entities like "Invoices," a rollup field on the Account can be used to calculate the total amount of all invoices associated with that account. This means that users can easily see aggregate data without needing to run separate queries or reports for every calculation across multiple records. The rollup field automatically updates at specified intervals and provides a real-time snapshot of the most relevant data insights.

Therefore, this capability enhances data management and visibility, allowing users to make informed decisions based on comprehensive information from related records.
