Auto update a Custom Attribute with the username upon state change.
I am trying to achieve a requirement, when the Defect WI is moved to the Closed State Then a Custom Attribute must auto populate with the username or login id of the User who performed the State Transition. So, an attribute must get auto filled with the username of the person who performs the Close state transition. Can we perform this using the Calculated Scripts or does it require a Follow up Action?
