Custom privilege associated to my BI Publisher query does not work from custom job.

We created a BI Publisher query to pull time and labor information into a report. We then created a custom privilege associated to an ESS process so the user can run this as a report from the ESS Scheduled Processes area. We added the privilege to a custom job role... Here is my question..

I run the process from the user with the custom job role, it errors out. I can see the process, run the process, but it errors out.

I run the process from a user that does not have the privilege, but has ESS Administrator and can see the process. It works perfectly. No problems.
