Which feature helps assign access to cases that have the same account as the user?

The feature that helps assign access to cases that have the same account as the user is the Sharing Set. Sharing Sets are specifically designed for community users to grant access to specific records based on their relationship with accounts, meaning users can access cases related to accounts they are linked to without needing to create complex sharing rules.

In the context of Experience Cloud, Sharing Sets simplify the process of determining record visibility for community members. By enabling access through their associated accounts, Sharing Sets ensure that users can efficiently view and manage cases related to their accounts, thereby facilitating better collaboration and case management within the community.

Role Hierarchy, Account Teams, and Sharing Rules, while significant features in Salesforce, operate differently. Role Hierarchy primarily deals with data visibility based on the organizational hierarchy and user roles rather than account-specific access. Account Teams provide a way for users to work with other team members on accounts but don't inherently assign access to related records like cases. Sharing Rules offer broader sharing capabilities across various record types but are not specifically tailored for managing access in relation to individual accounts, which is where Sharing Sets excel.
