Hierarchy Root Key

The Hierarchy Root Key is an optional key that is useful only when integration objects have a homogeneous hierarchy. You can use this key to improve performance. The Hierarchy Root Key should have only one field, Root Id, which EAI Siebel Adapter populates with the value of the ID field in the component instance that is in the root of the homogenous hierarchy. For example, assume quote Q1 has quote items A, B, and C where each of the quote items has child quote items (A1, A2, B1, B2,...). If you want to update the quantity requested for all quote items starting with the root quote item B, then it is faster if the data is denormalized. Using the Hierarchy Root Key, you can search for all records with Root Id equal to the Row Id of B and set the QuantityRequested field for each item.

NOTE:  When the business component is hierarchy enabled, then the wizard automatically sets the Hierarchy Parent Key for the complex integration component. To have a business component hierarchy enabled you need to set the property Hierarchy Parent Field.
