Creating Mappings in the Mapping Editor

You can create a mapping in the Mapping Editor by drag and drop or using the Create Mapping tool or contextual command. To generate default mappings between source and target objects that have the same name, right-click a data source and select Generate Default Mappings.

When objects in the Source and Target pane are mapped, any sub-objects that share the same name are automatically mapped as well. You can force the mapping with the Generate Mapping tool in the Sub-Object sub-tab of the Mappings pane.

• Mapping Examples
  This topic contains different mapping examples.
• Creating Forward and Reverse Mappings
  You primarily create mappings from one or more source models to the target model. These forward mappings define how to populate the objects of the current model with those of the data source model.
• Modifying the Default Mapping Syntax
  The Object Expression Editor dialog box allows you to build a textual or an XPATH expression from a list of objects.
