When trying to execute the BI Publisher Report using Process Scheduler; the App Engine calls BI Publisher.

Now the psae created at the O/S level by the Process Scheduler appears to include all the BI publisher activity within the process itself.

That is, each time the psae calls BI Publisher we do NOT see any other O/S level processes created.

Can we confirm/conclude that when BI Publisher reports are executed within PoepleSoft i.e Process Scheduler is self contained and runs only with PSAE process in the background (OS)
