Disable a field while creating ticket - To stop reporter from entering a value in the field

[Amrita Nair]

Hi, We have tickets raised by partners on our board. They add the root cause on the root cause field (which is something we would do after resolving the ticket). Is there a way to disable the field for reporters ?

build a Create screen and only put the fields you want entered at creation time on it.
