"Understanding Ownership and Visibility in Salesforce"

A.

Yes, it is possible for a user to own a record and not see it.

There are several ways this can happen in Salesforce, including:

1. Record-level access: A user's ability to view a record is determined by their record-level access, which is determined by their profile or permission set. If a user's profile or permission set does not grant them access to view certain types of records, they will not be able to see those records even if they own them.

2. Sharing rules: Sharing rules can be used to grant additional record-level access to certain users or groups. If a user owns a record but there are no sharing rules in place that grant them access to that record, they will not be able to see it.

3. Manual sharing: Users can also manually share individual records with other users or groups. If a user owns a record but has not manually shared it with themselves, they will not be able to see it.

4. Role hierarchy: The role hierarchy can also impact a user's ability to see records they own. If a user owns a record but it is higher up in the role hierarchy than their own role, they will not be able to see it.

It's important to note that even if a user can't see a record they own, they can still edit and delete it (unless their profile or permission set restricts those actions). Additionally, system administrators and users with the "View All" permission can always see all records, regardless of ownership or sharing rules.
