Lesson: 11 | Master-Detail Relationship

Notes

The Master Detail relationship is used when a user wants to manage the display of detail records based on the value reflected in the master record.

When a record of the master object is deleted, its related detail records are also deleted.
The Owner field on the detail object is not available and is automatically set to the owner of its associated master record. Custom objects on the detail side of a master-detail relationship cannot have sharing rules, manual sharing, or queues, as these require the Owner field.
The detail record inherits the sharing and security settings of its master record.
It is required on the page layout of the detail record.
By default, records can’t be re-parented in master-detail relationships. Administrators can, however, allow child records in master-detail relationships on custom objects to be reparented to different parent records by selecting the Allow reparenting option in the master-detail relationship definition.
It can be defined between custom objects or between a custom object and a standard object. However, the standard object cannot be on the detail side of a relationship with a custom object.
The data related to the object appears on a related list.
When we undelete the master record then all its related details records also get undeleted.

Note: Master-Detail relationship cannot be created where User or Lead objects are the master.
