Self Reference Lookup

File:Selfreflookup.gif

An Object can contain a Lookup field that references the Object itself (i.e. a self reference). This configuration is used to build record hierarchies (parent-child relationships between records) which are displayed in a Related Information section.

Examples

• An organization might have multiple subsidiaries, and some of those companies might also have subsidiary companies
• Employees have reporting relationships, to managers and subordinates
• In manufacturing, parts in a component might have subcomponents (or be part of of a larger component)

Considerations

• When a Self Reference Lookup field is added, a new section is added to Related Information

• The new section is named: <object> based Hierarchy View, where <object> is the Lookup Type, or object name; Learn more: About Objects in Lookup Fields
• The new section is added to all the Forms of the object
• By default, this new section is hidden
• When visible, this section displays a hierarchy view of the records

• A Self Reference Lookup field:

• Cannot reference itself, only other records in the object
• Is not supported in System Objects
• Is not supported in lookups to System Objects
• Is not supported in Object Inheritance models
• Can be deleted from the Fields tab in an Object
