Is there a way to limit the option of assigning an issue to certain users?

Is there a way to limit the option of assigning an issue to certain users, for example, when creating an issue, in the assignee field, I want to view a list of certain users instead of the whole company, is it possible?

What I want to be is whenever creating an issue, in the assignee field, only two users option.

Hi @Yousif Al Rawahi,

If you are doing this in a company managed project, the users you can assign an issue to is restricted by the assignable user permission in the permission scheme linked to your project.

So by limiting the users having that permission, you should be able to accomplish this.

In team managed projects, I am afraid Jira's permission settings are not fine grained enough to make this work.

Hope this helps!

I'm working on company managed project. 

Okay, if I want to apply it on main tickets only, is it possible?

Because I will be creating sub-tasks as well, main tickets will be assigned to one of two users (fixed), but in sub-tasks, it can be anyone.

In that scenario, my approach won't work of course. Restricting project permissions will apply to all issues in your project. In that case, you can revert to using workflow properties and use jira.permission.assignable on the statuses where you want to apply it.

Have a look at the documentation I linked on how to use it, but be aware that it is quite delicate and not very easy to maintain / document. I would dare ask myself if it is really necessary to implement these restrictions in the tool, as they will block you to apply backup scenarios if someone is ill or on holiday and you'll need to modify your settings each time the team changes.
