So I have a custom field for script runner called "Created by". I would to set this field by default to the current user when creating the ticket in service desk. I have found some forums, but they all seem outdate and I can not get it to work on Script runner. I am not looking for a post function, as I would like it to be prepopulated while creating the issue, or if it was hidden on the create screen and was set in the background as a post function after creating the ticket where I could then see that field in the People detials, that would work as well. Is there a way to achieve what I want?
