After you synchronize your tool's metadata with the tool map schema, you can add new objects to the SmartPlant schema in the Mapping Environment, which appears after you click OK in the Synchronize dialog box. To add a new object in the SmartPlant schema, navigate to the tool map class definition for the property or the map enumerated list that you created or to which you added new entries. On the Edit dialog box or the Edit Form tab, click the Publish or Retrieve tab, and then use the toolbar on the right side of the dialog box to add new objects to the SmartPlant schema. For more information about adding objects to the SmartPlant schema, see Extending the SmartPlant Schema.
