How to modify the title ID of a Issue

[yu wang]

I create a project name DWHD Agile Sustain .

The key of the project is DWHDA

Then I create a issue ,the ID of the issue is DWHDA-1

Now I want to modify the ID of the issue , let the ID change to the format ,such as "DEV201504001"  "DEV201504002"  , the format is "DEV+year+month+001"

Please tell me the method to solve this problem

+1 on Nic's answer. You can create a Custom Field, set it in a Post Function using SIL or Groovy and display that in many places. You can also programatically modify the Summary to start with the text you ask for, but not the ID/Key.

The short answer is "no"

To do this, you'll need to rewrite most of JIRA.  The whole system is hung off the key being of a certain format (project-sequence) and changing that means rewriting any code that handles it.
