Discrete job statuses describe the various stages in the life cycle of a job and control the activities that you can perform on it.
User Controlled Statuses
You can manually change user-controlled statuses. For example, you can change a job's status to Released to initiate the production cycle. Some user-controlled statuses are automatically changed based on other events. For example, when you complete a job, its status is changed to Complete.
You can assign a status of Unreleasedif there are no net issue, move, resource, completion, or scrap charges associated with the job and no purchase orders or purchase requisitions linked to the job.
Some job statuses are automatically updated by a process. For example, if you have the WIP:Define Discrete Job Form profile option set to concurrent definition, the job status is used to track the progress of the bill of material and routing load process. When you close a job, its status is used to track the progress of the concurrent close process.
