Self Reference Lookup

From LongJump Support Wiki

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
  • 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 Built-in or CRM objects
  • Is not supported in lookups to Built-in or CRM objects
  • Is not supported in Object Inheritance models
  • Can be deleted from the Fields tab in an Object

Note: For a Self-Referencing Lookup, you will generally want to set the Record Selection Type to Hierarchical, and then, for Select a Field for View, you will want to select the lookup field you are adding. However, the Hierarchical option can be selected only after the new self-referencing lookup field has been saved.

Then:

  1. Click the Forms tab
  2. Scroll to the Related Information Section
  3. Click the Display Settings link in the heading
  4. Move the object labeled: {object} based Hierarchy View to the Visible Objects area
  5. Click [Save]

Create a Self Reference Lookup between Records

  1. Navigate to the {object} tab (Company, for example)
  2. Edit a record, select a Parent Company from the lookup field and Save the record
  3. Select the record designated as Parent Company
  4. Scroll down to the Company based Hierarchy View section
Note that child Companies are displayed in the tree, demonstrating the relationships between records in the Company object
