We are using Scrum so rank all our user stories to create the backup. When we plan a sprint we create a version and on the planning board we drag the Jira into the right version for the sprint.
Doing this adds the right sprint name/version to the Fix Version field in Jira. I would like the ability for certain team leads to assign Jiras to different Fix Versions but for everyone else that field should be read-only.
How can I set security for that field?
