Execution Queue


The Execution Queue section allows monitoring processes, which are being handled by the process execution service, and shows execution errors.
This subsection is available only for those users, who has access to manage the process execution queue. These access permissions are assigned by the system administrator in Administration – Users – Access Settings – Global Access Settings – Processes – Allow to manage the execution queue.
