Is it possible to configure some fields editable or not editable when selecting a specific value for "Action" on the "Manage Employment" page, which is a classic UI Page?
For example, when selecting "Manager Change" for "Action", only manager field should be editable and other fields such as "Grade" field can not be editable.
If possible, please let me know how to do it briefly.(configuration screenshot and how to set-up)
