About the Multi-Value Field

The multi-value field is a business component field that contains the name of the multi-value link in the Multi Value Link property and a check mark in the Multi Valued property. All other business component fields are single-value fields. A multi-value field contains data from a record in the child business component because of the multi-value link.

If you must query the parent applet for all parent records that contain a child record that holds a field value, then you must use a multi-value field.

The following table describes some of the properties, as illustrated in the following figure, of the multi-value field.

Number (as shown in previous figure)	Property	Description
1	Multi Value Link	Identifies the multi-value link that provides values through the link from the child business component. A multi-value field in the parent business component contains data that Siebel CRM gets from the current record in the child business component through the multi-value link and link. The Column property of a multi-value field is empty because Siebel CRM gets values from the current record in the child business component rather than from the base table of the parent business component.
2	Field	Identifies the field in the parent business component that provides values for the field in the child business component. Siebel CRM provides these values through the multi-value link object and the link object.

As shown in the following figure, a link (1) contains the following properties:

• (2) Parent Business Component – (4) Source Field.

• (3) Child Business Component – (5) Destination Field.

In Viewing an Example of a Multi-Value Group Applet, the Street Address multi-value field in the Account parent business component contains data from the primary record of the multi-value field in the child business component.
