Answer 2

Use rollup fields

In Microsoft Dynamics 365, rollup fields are designed to help users obtain insights into data by monitoring key business metrics. A rollup field contains an aggregate value computed over the records related to a specified record, such as open opportunities of an account. Also, you’ll be able to aggregate data from the activities directly related to a record, such as emails and appointments, and activities indirectly related to a record via the Activity Party entity. In more complex scenarios, you can aggregate data over the hierarchy of records. As an administrator or customizer, you can define rollup fields by using the customization tools in the Dynamics 365 Web application, without needing a developer to write code.
