Program Type definitions (PTDs) are added to the Mapper through the Workflow Administrator. To open the Workflow Administrator, go to the Tools menu in the mapper and Select Workflow Administrator. ADT comes with a default set of PTDs that you can use/modify. You can also create your own set of Definitions and leave the standard ones in place. One you have finished adding/modifying the PTDs or if you chose the default definitions, you can then scan those definitions into the Metadata store so they are accessible by the Mapper application. Please review the online help in the Workflow Administrator for step by step details.
