You can export a Data Processor transformation as service and run it from a Data Transformation repository. You can also import a Data Transformation service to the Developer tool. When you import a Data Transformation service, the Developer tool creates a Data Processor transformation from the service.
When you import a Data Transformation service to the Model repository, the Developer tool imports the associated schemas to the repository. If you modify the schema in the repository, sometimes the changes do not appear in the transformation schema references. You can close and open the Model repository connection, or close and open the Developer tool to cause the schema changes to appear in the transformation..
