To ensure that reports and dashboards in your application correctly enforce user data visibility, you should:
1. **Adhere to CRUD and FLS Settings**: Ensure that the application respects the organization's Create, Read, Update, and Delete (CRUD) permissions and Field-Level Security (FLS) settings for both standard and custom objects.
2. **Respect Access Restrictions**: Design the application to align with the access restrictions set by the organization, ensuring that users only see data they are authorized to access.
3. **Handle Limited Access Gracefully**: Implement mechanisms to handle scenarios where user access is restricted, ensuring the application behaves appropriately.
4. **Custom Authorization Model**: If you use a custom authorization model, verify that it enforces data visibility in conjunction with Salesforce's sharing, CRUD, and FLS settings.
By following these strategies, you can ensure that your reports and dashboards enforce user data visibility effectively.
