About Multi-Value Links

This topic describes the multi-value link. It includes the following topics:

• How Siebel CRM Creates a Direct Multi-Value Link
• How Siebel CRM Creates an Indirect Multi-Value Link

A multi-value link is a child object of a business component. It describes the link that provides field values from the child business component that the multi-value group applet references. The multi-value link does the following:

• Defines the parent-child relationship that Siebel CRM uses to display fields from the child business component directly in the parent business component.
• Provides a field that resides in the parent business component with access to the values that the primary record of a multi-value group contains.

A parent-child relationship exists between the business component that the originating applet references and the business component that the multi-value group applet references. A link defines this parent-child relationship. The relationship between the two business components is one-to-many in the context of the multi-value link and multi-value group. A many-to-many relationship can exist. For example, between opportunities and positions. In the context of the multi-value group, Siebel CRM presents only one parent-child relationship.
