How do I add a field not listed in the "Add a Field" list?

[Rachel Starks]

I would like to add a hidden field to the request called "Order/PO Number". I, as the administrator, will fill this field out once I have the information. How can I add this as a hidden field into each request?

There is no point adding this field to the request if the user is not going to enter it, and you are not going to set up any automation to fill it for them as the request is created.

You say that you, as the admin, will fill it in later.  That's fine, but it suggests that the field should only be on the Jira issue that is behind the request.  So just add it to the issue, not the request.

Hello Rachel,

Without a plugin, there is no field level security in Jira.

However, you can think of a workaround with workflow permissions.

You can add "Self reflecting transitions" with a permission to admins only.  

Self reflecting transitions are the transitions in which origin and target statuses are same. For instance you add "Add Order/PO Number" transition to every status, and in the transition screen this field takes place. Only admins can execute this transition. You should remove this field from Edit screen of course.

This is the only solution I can recommend without a plugin.

Also, there is Field Security Plugin in which you can restrict fields.
