Another comment on extract vs. nonextract PVOs. The nonextract PVOs are used throughout Fusion Applications just not OTBI/BICC. They contain a lot of columns that are required outside of "reporting". The extract PVOs are scaled down to only include columns deemed required for reporting purposes.

If the VO is marked as customized then changes made by Oracle to seed data/starter selections will not get included in extracts. Best practice would be to edit/close (touch, don't need to actually make a change) to get the VO marked as customized. That way any changes coming from Oracle will not affect your extracts/jobs.
