Use the Populate wizard to add elements from the Target pane to the Spreadsheet pane. The Populate wizard creates child structures for the selected parent structure.
Using the Populate wizard
You can also use the Populate wizard to add target elements to the Spreadsheet pane when there are existing mappings. Any existing mappings are not altered by the wizard.
If the target map is a submap the Spreadsheet pane is populated by default with the selected element or attribute root. You can use the Populate wizard in the submap to add any child elements to the Spreadsheet pane in the same way.
