Click a destination element. The destination element node is displayed in the Mapping Expression Area.
Click a source element. The source element is displayed in the Mapping Expression Area.
You can click more source elements if required. This will display the selected source elements in the Mapping Expression Area.- Click the desired mapping expression. This displays a list of sub-functions associated with the selected mapping expression.
- Select the desired sub-function and use it to map the displayed source and destination elements.
- Once you have performed the mapping activity, click Save button to save the mapping.
Once you have mapped source and target elements, you can view and validate the generated mapping XSL, from the Data Mapper screen. You can also view the target XML and view and validate mapping output from this screen.
For details on using these mapping functions, refer to the section Using Mapping Functions.
