CloudOps Orchestration Service (OOS) allows you to delete an execution in a final state. If the execution that you want to delete is in a non-final state, such as Waiting or Running, you need to cancel the execution before deleting it.
Log on to the OOS console.
In the left-side navigation pane, choose Automated Task > Task Execution Management.
Find the execution that you want to delete and click Delete in the Actions column.
In the message that appears, click OK.
