The following diagram illustrates the lifecycle of a batch job submission record.
Pending Records are created in Pending status. Records in this state are put in a queue to be submitted.
Canceled Users may Cancel a pending record to prevent the batch job from being submitted.
Started Once a pending record has been submitted for processing, its status will be changed to Started. Records in this status may not be canceled.
Ended When the batch job has finished processing, its status will be changed to Ended. Note that records in Ended status may have ended in error. Refer to Batch Jobs May End in Error for more information.
