Cancel a process
To stop a runaway job or a process that never started this is the process to follow:
GO > PeopleTools > Process monitor
Once the monitor opens up you will see your ID in the Operator ID field.

Scroll down through the listing of your jobs and when you find one that is “stale” (over a week old) and it is in a status of queued, processing, initiated or error it needs to be stopped. Double click on the job and a window will display.

Select the cancel option from the right hand column of "Update Process" and click Apply on the bottom right.
When you go back to the main process monitor and “kick the dog” it will refresh the status for you to cancelled. If you want to remove it entirely you can select it again and repeat the process but this time choose delete. Then click the Apply button on the bottom and refresh the screen.
