# Cancelling Workflow Tasks

When a Workflow is running, HPE Morpheus Enterprise offers the capability of cancelling a Task and stopping any subsequent Tasks from starting. When viewed later in History or Executions, this leaves the Task and Workflow in a cancelled state. This is useful if you have a very long-running Task that you know will fail and wish to cancel or if you want to prevent a “retryable” Task from running again.

To cancel a Workflow, open the execution. Within the running Task will be a cancel button, click the button to interrupt the Workflow. Once cancelled, see that the Workflow and Task are now considered to be in a cancelled state which is shown in the UI. At this point the cancel button becomes a retry button and the Task could be resumed if desired.

NOTE

Cancelling a Task doesn’t actually interrupt the process already running on the workloads themselves. It simply interrupts the Workflow and stops it from continuing. Behind the scenes, HPE Morpheus Enterprise allows the running process to complete or time out rather than risk corrupting data with a non-graceful interrupt.
