Is there a way to configure users in a project so that they cannot be assigned issues?

[Jeff Humphry]

I have some executive type users in my JIRA project that are only there to review and create tickets, but should never be assigned a ticket. Thanks!

I suggest using project roles and put them in a role that the permission scheme doesn't allow the role to be assigned tickets. You can also give the role create and browse only if you don't want them to be able to edit tickets once created. 

Since you're new here is some other guidance that may save you problems down the line. 

JIRA works by GRANTING access. You can't restrict access. By default, it grants access to the group used to logon (used to be JIRA-users but may be different on your version).  This is probably where you're getting the permission to everything from. .

1. The FIRST thing you need to do to get control is to remove any groups with logon privileges from the permission scheme unless you absolutely want everyone to have that permission.
2. Then I suggest you setup Project Roles for the various functions like, tester, QA, Browse Only, etc.
3. One permission scheme will cover almost all projects. The project admin controls project role membership

Thanks gentlemen, I'll check these out. I'm not that familiar with JIRA permissions schemes, so it may take a bit. I think our admin is just using defaults.

Hi Jeff,

did you have a look at the permission scheme of your project? There's one available called "Assignable user".

Best, Max
