Explanation
Cancel an executing batch job
Complete the following steps to immediately cancel the running task.
Go to System administration > Inquiries > Batch jobs.
Select a batch job that has a Status of Canceling.
On the Batch tasks tab, select Abort on the task, and then select OK.
Note: Sometimes canceling a batch job can take a long time if already executing tasks will take a long time to finish. This option provides a system administrator or batch job manager with the ability to cancel already executing tasks for jobs that are in the process of being canceled. This provides a much faster mechanism to cancel a long running job that is impacting system usage elsewhere.
