How to make custom field as read-only

[Diogo Rodrigues]

I've a custom field A that is dependent on field B and field C.

I've an automation to whenever B and C are updated it updates A.

However it is possible to manually edit A. 

How can I set field A as read-only?

In creation form I can add it as read-only but it move always to the end of the list, I cannot decide the position of it.

in issue view; I cannot make it read-only,

Hi Diogo,

If you create a separate Edit screen from the Create screen and then remove the field from the Edit screen, then users will not be able to edit it on the screen.
