Using the Data Palette of the Mapper

The Data Palette of the mapper provides a location to access the variables and their subelements. You can drag-and-drop variables or their subelements from the Data Palette of the mapper into the Constraints and Target Expression tabs of the mapper.

Note: You can also drag-and-drop elements from the Source pane of the mapper directly into the Constraints and Target Expression tabs of the mapper.

The following types of variables are displayed in the Data Palette of the mapper:

Caution: The Data Palette of the mapper displays a different set of variables than the variables displayed in the Data Palette for business processes (JPDs). The variables displayed in the Data Palette of the mapper are used only in transformations and are distinct from the variables used in business processes.
