Is there any way for the ticket counter to be independent of Incidents and Service Requests? I mean

[Victor Manuel Valencia Mejia]

When I create an Incident Ticket the Project Key is MHDT-1, after that I will create a Service Request, and the project key will be MHDT-2, in the same Project obviously. My company suggests that the sequential number be independent between Incidents and Service Requests. 
Is this possible?

Hi @Victor Manuel Valencia Mejia 

Sadly, this is not possible. The Jira key is associated with a work item, not its type. and is one per project.

You will need to create another project to have a different Key.
