THIS is what I was looking for! Thank you, Chuck.
ServiceNow is such a black box for partial-devs like myself. We only have access to scripting in the PA modules (platform/performance analytics) but that leaves a lot not visible to us.

Hi!
1. What is 

UpdateProjectTaskWBS

 ?
2. If we use "child" in script after child.query, is it the whole GlideRecord('pm_project_task') or only the part of table after query?
