The  mapping is another copying and synchronization capability of DataHub to locate or find a node’s type in the target so that you can map a node’s type from the source to the target correctly. If your previous mapping mode is the Define Target Type from Attribute Value mapping, it will be used as the default mapping mode automatically. You can update the target types and attribute values in the Define Target Type from Attribute Value dialog.

Enabling the Define Target Type from Attribute Value Mapping

If you previously mapped a schema and copy data using the  mapping mode, you will have the same mode open as the default mapping mode automatically in the next time you open the Cameo DataHub Schema Map Manager dialog. Therefore, the Export Schema Map Wizard dialog no longer opens next time you copy data. If you do not want to map in this mode, you can click to disable the Define Target Type from Attribute Value mapping mode in the Cameo DataHub Schema Map Manager dialog.
