Creating a Link

The relationship between houses and house renovations is one to many (1:M); there can be many renovations recorded for one house. Therefore, you need a link to create the parent-child relationship between the Internal Product business component and the NREC Renovations VBC business component. Internal Product is the business component that NREC is using to store houses. See NREC's entity relationship diagram shown in Figure 3.

To create a link between parent and child business components

1. Select the Link object type.
2. In the Links window, add a new record as shown in the following table.

   Field	Value	Description
   Name	Internal Product/NREC Renovations VBC	Unique name for the link.
   Project	NREC Configuration	Project to which the object belongs.
   Parent Business Component	Internal Product	Parent business component.
   Child Business Component	NREC Renovations VBC	Child Business component.
   Source Field	Part #	Unique ID on the parent record. Often this field is Row Id. In this case, the unique field is a manually entered value.
   Destination Field	House_ID	Column in the child record that stores the parent ID.
