Hide custom field from users, but set programmatically

[Marcel Höll]

I want to have a custom field, which is hidden for all users, but set through ScriptRunner while updating an issue. Is there any possibility to do so?

What configurations do I have to set, to get field "settable" programatically, but don't show it up the users, but use it in filters?

Thank you in advance.

To "hide" it, remove it from the issue screens (create, view, edit and transitions)

Post functions and listeners do not care if a field is not on a screen, they can still set and clear them, so Scriptrunner can be used to simply say "set field to something" whereever you need it to.
