case status
Case status is the primary indicator of the current state of your business process. By using case statuses, you communicate progress to people involved in a case processing to ensure a common understanding on a way to reaching your business objectives. For example, you can use a status In-Progress to communicate that a case worker is working on a case, and Resolved-Completed to announce that the case reached a successful resolution. You can use default statuses, or you can create custom statuses to meet your unique business needs.
