Object Relationships

> Customization > Objects > {object} > Object Relationships

The Object Relationships page shows how an object relates to other objects.

Child Objects

Click an existing Child Object to visit it, or click [New Child Object] to create a new one.

The relationship grid displays objects that are related to the current object by Lookup fields, and shows how the objects are related:

In the Cases object, for example, in the Object Relationships the relationship grid contains lines that look something like this:

Relationship Type	Object	Alias	...
Many to One	Accounts

The way to read that line is "Many (Cases) to One (Account)". Or, in general terms:

"Many (of the current object) to One (of the object on this line)"

The grid columns show:

Column	Content
Relationship Type	Cardinality of the relationship: One to many, many to one, or many to many.
Object	The object at the other end of the relationship. Click this link to Manage the Object Relationship.
Alias	The name given to the relationship, for use in Composite Object operations.
Junction To	If the relationship is many to many, then the object is a Junction Object. This column gives a link to the object on the other side of the junction.
Cascade Rules	In this section, you establish the Cascade Rules that govern Composite Object operations.

To change an object relationship, click the name of the related object in the grid.

Considerations

For Many to One relationship, only Alias and Update Cascade Rule is available to update
Relationship Alias is a required field and it should be unique for a given base object
- Alias cannot be "Users" or "User"
- A Relationship Alias can only contain alphanumeric characters or the underscore (_) character

Relationships are formed by Lookup fields. To delete a relationship, delete the lookup field that created it.
