About the MVG Business Component

This business component stores the detail records of the master-detail relationship with the originating business component. The records displayed in the multi-value-group applet are from the multi-value group business component.

The multi-value group business component has no important properties with respect to its role in the implementation of a multi-value group. It has field child object definitions that are used in the following ways:

• To store data for a field in the multi-value group

  Each field with this role is represented by a list column in the multi-value group applet. It may also participate in the multi-value link to supply data to a corresponding field in the originating business component.

• To identify the primary record in the multi-value group

  Primary records are identified by the primary field which is specified in the Primary Field Id property in the multi-value link.

  NOTE:  The primary field has nothing to do with the multi-value group business component. It does have relevance to the originating business component, the multi-value link, and the multi-value group applet.

• As the destination field of the link

  The field with this role is a foreign key to the originating business component.
