Can a table have multiple editioning views in Oracle RDBMS 11
You can only have one editioning view per table in each edition.

To explain, some background. Edition-based redefinition (EBR) brought two new schema objects:


Editions
Editioning views


Editions extend the namespace for an object. This prefixes the schema. So the fully-qualified name of an object in Oracle Database from 11.2 is:

edition_name.schema_name.object_name


But you can't explicitly reference the edition_name. It is part of your session settings. When you create an editionable object, it goes in your current edition. 

For example, the following creates a new user, editions enables it, creates the table "abc" and the editioning view "ABC":

grant create session, create table, create view, unlimited tablespace to
  usr identified by usr;
alter user usr enable editions;

create edition e1;

grant use on edition e1 to usr;

conn usr/usr

create table "abc" (
  c1 int, 
  c2 int
);
create or replace editioning view abc as 
  select * from "abc";

select object_name, object_type, edition_name
from   user_objects;

OBJECT_NAME   OBJECT_TYPE   EDITION_NAME   
abc           TABLE         &lt;null&gt;         
ABC           VIEW          ORA$BASE     


If you try and create a new version of the view in the edition e1, you'll get an error:

create or replace editioning view e1.abc as 
  select c1 from "abc";

ORA-01917: user or role 'E1' does not exist


This is because you're currently in the edition ora$base. The default for every database. 

To create a new version of the view, you need to switch your session to edition e1:

alter session set edition = e1;

create or replace editioning view abc as 
  select * from "abc";

select object_name, object_type, edition_name
from   user_objects;

OBJECT_NAME   OBJECT_TYPE   EDITION_NAME   
abc           TABLE         &lt;null&gt;         
ABC           VIEW          E1   

select object_name, object_type, edition_name
from   user_objects_ae;

OBJECT_NAME   OBJECT_TYPE   EDITION_NAME   
abc           TABLE         &lt;null&gt;         
ABC           VIEW          E1             
ABC           VIEW          ORA$BASE     


As you see, you now have two views "ABC". One in each edition.

If, still in E1, you try and create a new editioning view using "abc", you'll get an error:

create or replace editioning view abc_new as 
  select * from "abc";

ORA-42300: an Editioning view is already defined on this table
