Hi,
You do not really cut and paste the parameters from one stored process to another. However, you can make a copy of the entire stored process, give it a new name and then edit the parameters to add or change parameters, as needed. You might consider contacting Tech Support for more specific help in this task, because the steps that you would follow would be different depending on whether you were using the Stored Process Wizard in EG or whether you were manually registering the Stored Process in SAS Management Console.
Good luck!
