What is ctask in servicenow?

Navigate to Change > Open. Hi, Any one pls tell me the difference between 'catalog task' and 'task' tables, is both are same?. Hello, I have been given a fairly comprehensive set of workflows for CHG tickets and one of the things that the team would like is to use the CTASK state to. We have a process where once a user creates a new Change Record and Saves it or submits it for approval, they can then create Change Task. Tasks are not created directly on the task table. Tasks are assigned to users or groups as part of the fulfillment process when that item is ordered.
