How to prohibit EDITing ticket to current assignee?

Chozo

Hello all,
I'd like to ask you about my problem.

I've got a subtask in Jira and I would like to prohibit editing ticket (edit screen) to current assignee, but just for him (administrators etc. can do).
So it means, assignee of current subtask can do only Accept/Decline solution

Thanks for advices!
Hit me up, if you will need more informations, thanks!

Hi @Chozo

You can restrict edit access using project permissions. This does apply to the whole project though - rather than one specific issue type.

To achieve the above you'll need to modify the project's permission scheme - to do this you'll need to be a Jira Admin / Site Admin and then:

1. Go to Jira Administration > Issues > Permission Schemes (on left-hand menu)
2. Select the permission scheme for your project
3. Remove access to each permission you would like to restrict - for example, "Edit Issues" impacts modifying issue fields whilst "Transition Issues" impacts who can change the status. Remove access using the hyperlink next to each permission
4. Press Edit next then press "Show More" - select "Current Assignee" and select which permissions they should receive
5. Ensure Admins also have these permissions

^ This allows you to modify which permissions are restricted based on a user picker, and which are not.

-------------------

Alternatively, you can limit some edit rights for one specific issue type using advanced workflow configuration - specifically conditions.

To use these you'll need the sub-task to have its own workflow (or it'll apply to all issue types using that flow) - and then as a Jira Admin:

1. Go to Jira Administration > Issues > Workflows
2. Locate and edit the sub-task workflow in Diagram mode
3. Select an appropriate transition and in the pop-up window, press Conditions
4. Choose the "Only Assignee" condition and press Add
5. Publish the new workflow

^ This ensures only Assignees can transition the issue - but it won't cover all edit functions like permissions will. You can add to these conditions to include Admins, such as using "Permission Condition", "User in Group" or "User in Project Role"

You can expand this into status properties (select a status and press Properties in the pop-up window) which does cover more permissions - see this help page for how these work, and see if one of these works for you.

-------------------

Your final option is to use issue-level security - but this does stop users viewing the issues also, not just editing them.

If you need help with any of these, let us know
