Enabling ranking allows you to rank issues on a board by drag-and-drop, and to create sprints. It also enables GreenHopper to group sub-tasks together underneath their parent issue.

Enabling Ranking

1. 
   Note that only the owner of a board (or a person with the 'JIRA Administrators' ) can configure a board.
2. Click the 'Filter tab.

3. Click the 'Add Rank' button. This will append the following to your filter's query:

   ORDER BY Rank ASC

     automatically creates a custom field called Rank, of type Global Rank (see GreenHopper JIRA Configuration). Please ensure that your JIRA instance contains only one custom field called Rank, and that the Rank field is assigned to the global context (i.e. not to specific issues or projects).
