Northern Trail Outfitters has two custom objects that are part of a master-detail relationship.

The Owner field on the Master record determines the ownership and sharing access of the detail record in a master-detail relationship. According to the Salesforce documentation, “The detail record inherits the sharing and security settings of its master record.” The default owner is not set in the parent object’s settings, the Owner field on the Detail record does not exist, and the owner is not set independently on the detail object’s settings.
