What is a capability of cross-object formula fields?

1. They can expose data the user does not have access to in a record.

2. They can reference fields from master-detail or lookup parent relationships.

3. They can be used in three roll-up summaries per object.

4. They can reference fields that are 10 relationships away.

The correct answer is: They can reference fields from master-detail or lookup parent relationships.

Cross-object formula fields are a powerful feature in Salesforce that allows users to access and display information from related records in a single formula field. The key capability is that they can reference fields from master-detail or lookup parent relationships. This means that if you have a relationship set up where one object (the child) is linked to another object (the parent), you can create a formula field on the child object that pulls data directly from the parent object. For instance, if you have a custom object that represents an Order and another object that represents a Customer, you could create a formula field on the Order object that displays the Customer's name. This functionality enables users to create more dynamic and informative records by displaying related information without the need for additional queries or logic. This capability enhances the usability and data representation within Salesforce, making it easier for users to access relevant information that supports their decision-making processes. Thus, the ability to reference fields from master-detail or lookup parent relationships is central to the functionality of cross-object formula fields.
