What is the maximum number of roll-up summary fields allowed?

1. 10

2. 20

3. 25

4. 30

The correct answer is: 25

The maximum number of roll-up summary fields allowed on a child object related to a single parent object is indeed 25. Roll-up summary fields are a powerful feature in Salesforce that allow users to aggregate data from related child records, such as calculating totals or counts based on specific criteria. This ability is particularly useful for maintaining accurate and up-to-date summaries at the parent record level without the need for complex formulas or manual updates. In practical terms, having up to 25 roll-up summary fields provides a significant level of flexibility for a Salesforce admin to design data relationships and reporting structures. It allows for a diverse range of calculations and insights to be captured, all while keeping the data model streamlined. This limit is set by Salesforce to balance functionality with performance considerations, ensuring that the system remains efficient even as more roll-up fields are added. This understanding is crucial for Salesforce Admins who need to design systems that leverage these fields effectively while staying within the constraints set by the platform.
