Sometimes the wrong files may be submitted, or rules are not yet fully configured, leading to runs taking a long time to process. This can hold up other processes and cause delay to your mission-critical operations. You can stop that run.
You can assign Run stopper role for this action in process permission so that you can restrict who can stop an ongoing run for each process. Any user with permission can stop the run while it is queuing or running before the matching process is finished.
