Oracle Error Message
ORA-42300: an Editioning view is already defined on this table
Reason for the Error
An attempt was made to create an Editioning view on a table on which another Editioning view is already defined in the same Edition. This violates a restriction that at most one Editioning view may be associated with any base table in a given Edition.
Solution
Create the new view as a regular view or, if the view being created is really intended to be an Editioning view associated with this table, drop the existing Editioning view before creating the new one.
