Materialized views with fast refresh

Materialized views with fast refresh

Hi

I've been trying to run materialized views from one database to another, ie the
master
tables are not in the same instance as the mat views. I'm using a database link
to
reference the tables in the remote database.  If I use a materialized view
referencing
only one table the view is created ok but as soon as I put a join in the view
it fails
with the error

ORA-12015 (See ORA-12015.ora-code.com) -cannot create a fast refresh materialized view from a complex query.

I've googled on this and made changes to the log creation so to include rowid
and used
these in the select with the join but still get the same error.

If I create the materialized view (using same code with joins) within the same
database
as the logs it works ok.  

Is this a limitation of materialized views or is there something fundamental
that I'm
missing.

I've included the code below.

Thanks for any help

Niki

CREATE MATERIALIZED VIEW LOG ON qlsdba.stcstatd
WITH SEQUENCE,ROWID
INCLUDING NEW VALUES;

CREATE MATERIALIZED VIEW LOG ON qlsdba.stcsessd
WITH SEQUENCE, ROWID
INCLUDING NEW VALUES;

CREATE MATERIALIZED VIEW busfeed.stcstatd_stcsessd_mv
REFRESH FAST ON DEMAND

SELECT
       a.rowid AS stat_rowid
,       b.rowid AS sess_rowid
,       a.aos_code AS curr_code1,
       b.aos_code AS curr_code
,       b.aos_period AS curr_occurrence
,       b.acad_period AS acad_period
/*,     a.full_desc AS curr_full_desc */
/*,     a.short_desc AS curr_short_desc */
/*,     a.dept_code AS dept_code */
/*,     a.aos_type AS curr_type */

       qlsdba.stcstatd@(protected) a,
       qlsdba.stcsessd@(protected) b

       b.aos_code = a.aos_code /*
