Explanation:

  • The workflow makes use of an If Instruction to check a previous job's return values. See JS7 - If Instruction for details of how to add expressions to If Instructions.
  • If the If Instruction evaluates to true then the Fail Instruction is executed. The order is then assigned the FAILED state.
  • When an order is failed, a message and a return code that specify the reason for failing the order can be added as an option.
  • The operation to fail an order can be specified being Uncatchable indicating that a surrounding Retry Instruction will not be triggered. Instead, the order will be moved to the position after the Retry Instruction and will halt with a FAILED state.
