  • SuccessorID: Specifies the NodeIDs of jobs that are direct successors of the current job. If more than one job is specified then they will will be executed in parallel. NodeIDs in this column are separated by a space.
  • Instruction:  Makes use of the fixed value Job. This column is reserved for later support of further JS7 - Workflow Instructions.
  • Name: Specifies the job name.
  • Description: Optionally specifies a descriptive title for the job.

  • Script: Specifies the job script that will be executed. Multiline input is allowed.
  • Error Handling: Specifies one of the following options for JS7 - How to apply error handling:
    • STOP: If the job fails then the order will be put to the FAILED state and will remain with the job. Failed orders require user intervention to resume, to suspend or to cancel the respective order.
    • IGNORE: Any job error is ignored and order processing continues, see JS7 - Try-Catch Instruction.
    • RETRY: The job will be retried in case of error for 3 times with a delay of 60s, see JS7 - Retry Instruction.
    • LEAVE: The order will leave the workflow with an unsuccessful History outcome, see JS7 - Finish Instruction.
