M. View Fast Refresh

[Thomasps]

All,

I am creating a Materialized view using joining of two tables. When trying for the FAST refresh, getting the message

SQL> exec dbms_mview.refresh('crew_log','F');
BEGIN dbms_mview.refresh('crew_log','F'); END;

*
ERROR at line 1:
ORA-12004: REFRESH FAST cannot be used for materialized view
"REPLDBA"."CREW_LOG"
ORA-06512: at "SYS.DBMS_SNAPSHOT", line 794
ORA-06512: at "SYS.DBMS_SNAPSHOT", line 851
ORA-06512: at "SYS.DBMS_SNAPSHOT", line 832
ORA-06512: at line 1

Originally my understanding was, FAST refresh is not possible on M. Views based complex queries ( M. Views with joins and functions). But please see the following link

I have Oracle 9.2.0 in both ends and the OS is IBM AIX. M. View logs as well created. If the above link is true, why I am getting the problem?

Many Thanks
