Mapping Line Items

Next, look at the Line Item component.

The record defines its parent as Header, so it is invoked as a child of the Header component.

To improve performance, use simple buscomps instead of the line item buscomps used in the Siebel Call Center user interface. These improve performance because they are light-weight and, most important, because they are not defined as hierarchical buscomps.

Because they are not hierarchical, you must define their hierarchical parent fields in the mapping, using the Data Map Field records with Root Quote Item ID and Parent Quote Item ID in their Source field.

Both these records use the advanced option with the name ID Mapping Component to define the foreign keys to define hierarchical parent fields.

NOTE:  For backward compatibility, the application retains the advanced option MapId, which functions like ID Mapping Component.

For more information, see Configuring Event-Based Commands for DTU.
