Subject: Can't create simple MV with FAST refresh

Hi all,

Using 8.1.7.4.0 on HP/UX with COMPATIBILE set to "8.1.7", I'm not able to
create the following simple MV:

	CREATE MATERIALIZED VIEW qt_gl_trans_ab_mv
	TABLESPACE qt_mat_view
	BUILD IMMEDIATE
	USING INDEX TABLESPACE qt_mat_view PCTFREE 15 INITRANS 2  
	REFRESH FAST WITH ROWID
	USING LOCAL ROLLBACK SEGMENT rbsbig  
	START WITH SYSDATE 
	NEXT (TRUNC(SYSDATE+1) + 4/24) 
	AS
	select fiscal_year, fiscal_period, account_no,
		trans_type, trans_amount
	from my_general_ledge
	where trans_type in ('A','B')

It errors with ORA-12015 "cannot create a fast refresh snapshot from a
complex query".  According to MetaLink doc 179466.1, a complex query in a MV
on 8.1.7 is one that has at least one of:

	- a distinct or unique keyword
	- an aggregate function (e.g. avg, count, max, min, sum, ....)
	- a connect by clause
	- a group by or order by clause
	- a set operator (UNION, UNION ALL, INTERSECT and MINUS)
	- joins other than those in a subquery

But my query has none of those?  Thinking somethings hosed or I'm completely
misunderstanding the "IN" operator of the WHERE clause, I tried "where
trans_type = 'A'", but with the same results.

Also, I've created the MV log for the fast refresh:

	CREATE MATERIALIZED VIEW LOG ON my_general_ledger
		WITH  ROWID

I'm just testing out MVs here, but I'm missing something real simple and/or
stupid here, but for the life of me I can't see what (even after a lunch
break).

Anyone?
