About Multi-Value Links

This section describes multi-value links. It includes the following information:

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

A multi-value link (MVL) 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 (MVG) applet references. The MVL 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 MVG contains.

A parent-child relationship exists between the business component that the originating applet references and the business component that the MVG 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 MVL and MVG. A many-to-many relationship can exist – for example, between opportunities and positions. In the context of the MVG, Siebel CRM presents only one parent-child relationship.
