Obsolete transformations can be deleted from the Administration Site.
Note: You cannot delete an active transformation that is currently being used for either a changed data transformation or a bulk data transformation.
Perform the following steps to delete a transformation:
Click Manage.
The Source Database Hosts pane and the Details pane appear. The hosts associated with the deployed transformations appear in the Source Database Hosts pane.
In the Source Database Hosts pane, expand the host type, and then the host to view the list of source databases.
Select the source database associated with the transformation that you want to delete.
The Transformations Source pane appears to the right.
In the Transformations Source pane, click the Transformations tab.
Select the check boxes corresponding to the transformations that you want to delete.
Click Delete.
The transformation is deleted from the list of transformations appearing on the Transformations tab.
Note: If you delete all transformations for a specific source database, then the transformation source associated with the deleted transformations is automatically removed from the Source Database Hosts pane.
