I am trying to recreate the process “CREATE_CHUNKS_BY_ROWID”
https://oracle-base.com/articles/11g/dbms_parallel_execute_11gR2#create_a_task
but failed.
I follow the following steps:

 CONN / AS SYSDBA
 GRANT CREATE JOB TO test;  
  /        
 CONN test/test
  /
  DROP TABLE test_tab;
  /
  CREATE TABLE test_tab (
   id          NUMBER,
   description VARCHAR2(50),
   num_col     NUMBER,
   session_id  NUMBER,
   CONSTRAINT test_tab_pk PRIMARY KEY (id)
      );
      /
  INSERT /*+ APPEND */ INTO test_tab
   SELECT level,
   'Description for ' || level,
    CASE
    WHEN MOD(level, 5) = 0 THEN 10
    WHEN MOD(level, 3) = 0 THEN 20
        ELSE 30
          END,
         NULL
    FROM   dual
    CONNECT BY level <= 500000;
    COMMIT;
      /
    EXEC DBMS_STATS.gather_table_stats(USER, 'TEST_TAB', cascade => TRUE);
     /
     BEGIN
      DBMS_PARALLEL_EXECUTE.create_task (task_name => 'test_task');
     END;

When doing this step

    BEGIN
  DBMS_PARALLEL_EXECUTE.create_chunks_by_rowid(task_name   => 'test_task',
                                               table_owner => 'TEST',
                                               table_name  => 'TEST_TAB',
                                               by_row      => TRUE,
                                               chunk_size  => 10000);
    END;

i get the following errors:

ORA-29491: invalid table for chunking
ORA-06512: at “SYS.DBMS_PARALLEL_EXECUTE”, line 28
ORA-01403: no data found
ORA-06512: at “SYS.DBMS_PARALLEL_EXECUTE”, line 14

29491. 00000 – “invalid table for chunking”
*Cause: An attempt was made to chunk a table by ROWID, but the table was not a physical table or the table was an IOT.
physical table or the table is an IOT.
*Action: Use a table which has physical ROWID.
