Copying transaction Incident Template (IT Service Mgmt.) to transaction Incident (IT Service Management) is not maintained in Customizing

I am utilizing SAP WebClient with transaction type SMIN to create Service Desk Incidents. I have created a Template Incident within Webclient.

I want to create an Incident Message using a Incident Template that I have created. When I select Create--> Incident and then select the "New from Template" icon, I click on the template I have created, I receive the following message:

Copying transaction Incident Template (IT Service Mgmt.) to transaction Incident (IT Service Management) is not maintained in Customizing

What is the meaning/ method of fixing this error message?

Thanks
