Creating a Data Object Node 

Use

A data object node serves as a container of business data. You can create the following types of nodes for a data object:

·        Root node

This is the first node in the node hierarchy. A data object can have only one root node.

·        Child node

When you create a new node under an existing node, it is called the child node.

When modeling a standard data object, you ought to reflect the structure of the corresponding business object in the back end to prevent loss of data.
