Why is an order history entry red?
An order does not know whether a job in the job chain has finished successful terminated successfully or with an error. An order knows only its own state (step in the job chain).
...
If the state of the order is an error_state of a job chain node at the same time, then it is assumed that a job in the job chain was faulty and the entry in the history is shown displayed in red. Otherwise the color of the order in the history is black.
