If you want to duplicate a model that has been checked into the
repository, you must first check it out and then save it as a new model (with a new
GUID).
Select the model to duplicate in the repository, right-click
it, and select Check Out to check it out
into your local workspace.
Select the model in your local workspace and click File > Save as New Model.
Select an appropriate folder and filename and click Save to create the duplicate model.
Note: The duplicate model replaces the original model in the
workspace, but you can verify that the duplication has succeeded by reading
the new path in the PowerDesigner window title bar.
Right-click the duplicate model and select Check In to
open the Check in Document dialog.
Specify the folder to check the model into and any other check-in options (see
Check-In Parameters), and click
OK.
