Business View Rules
Do not remove columns from existing business views. Changing business views that applications use can cause unpredictable results when you run the application. If you need to hide columns, do so at the application design level using either FDA or Report Design. Performance is not greatly improved by deleting a few columns from a business view.
An update preserves these changes:
New custom business views.
New columns, joins, or indices to the existing business views.
An update replaces columns that you have removed from JD Edwards EnterpriseOne business views.
