Creating a Link Between Houses and House Renovations

This task is a step in Process of Configuring Siebel CRM to Use Data From an External Data Source.

The relationship between houses and house renovations is one-to-many. A user can add many renovations for one house. NREC uses the Internal Product business component to store houses. To create the parent-child relationship, you must add a link between the Internal Product business component and the NREC Renovations VBC. For more information, see Design Strategy for the Data Layer.

To create a link between houses and house renovations

1. In the Object Explorer, click Link.
2. In the Links list, add a new record using values from the following table.

   Property	Value
   Name	Internal Product/NREC Renovations VBC
   Project	NREC Configuration
   Parent Business Component	Internal Product
   Child Business Component	NREC Renovations VBC
   Source Field	Part #
   Destination Field	House_ID

   The source field is the unique ID on the parent record. This property is typically Row Id. In this example, the user enters the unique field.

   The destination field is the column in the child record that stores the parent ID.
