Generate Hyperlink and Open external url using a field value as a parameter ?

SOLVED

In my Ticket screen, I need to "transform" the content or the title of one field to a hyperlink that opens an internal URL made with a static part http://myjiraurl/jira/browse/[Ticket_No]

http://myjiraurl/jira/browse/JIRA_Incident_Nr_Field_Value

As an example, this ticket would generate the following url : http://myjiraurl/jira/browse/45986

Is it possible ? Where should I implement that ?

Thank you for your advice
