I finally created the MView and a function called MY_MV_CAPABILITIES per http://www.sqlsnippets.com/en/topic-12884.html

But it says "Not Capable of: REFRESH_COMPLETE" - how can that be?  

SQL> select my_mv_capabilities( 'SELECT * FROM S_MV_1', 'REFRESH' ) as mv_report from dual;  

MV_REPORT

---

---

 

Not Capable of:  

  REFRESH_COMPLETE     no primary key constraint in the master table  

  REFRESH_FAST     REFRESH_FAST_AFTER_INSERT     BTPMUSER.S_MV_1     the detail table does not have a materialized view log  

  REFRESH_FAST_AFTER_ONETAB_DML     see the reason why REFRESH_FAST_AFTER_INSERT is disabled  

  REFRESH_FAST_AFTER_ANY_DML     see the reason why REFRESH_FAST_AFTER_ONETAB_DML is disabled
