You can manually create a target definition rather than importing it or creating it from a source definition.
To manually create a target definition:
In the Target Designer, click Targets > Create.
Enter a name for the target and select the target type.
If you create a relational definition, follow database-specific naming conventions.
Click Create.
An empty definition appears in the workspace. It may be covered by the dialog box. The new target definition also appears within the Navigator window.
If you want to create another target definition, enter a new target name and target type and click Create. Repeat this step for each target you want to create.
Click Done when you finish creating target definitions.
Configure the target definition.
The new target definition is saved to the repository. You can now use the target definition in a mapping.
You can also create a target table in the target database based on relational target definitions.
You cannot manually create a target definition for XML files.
