How can a user access a child record from a parent record when a parent-child relationship exists?

A user can access a child record from a parent record through a related list. In Salesforce, a related list is an area on a parent record's detail page that displays related records from a child relationship. This allows users to view and interact with child records directly within the context of their parent record.

Related lists provide a user-friendly interface for quickly accessing the various child records associated with a parent record, which enhances navigation and usability within the Salesforce platform. This is especially important in managing relationships between different entities, such as accounts and their related contacts, opportunities, or cases in Financial Service Cloud.

Other options, such as a lookup field, can also allow users to establish relationships, but they do not provide a direct way to view child records directly on the parent record's page. A custom link might redirect users to another page, and a child field is not a recognized way to access child records in this context. The related list simplifies the process and keeps information organized and accessible.
