Materialized View Not Refreshing

Question

Hello,
I have a materialized view that is not refreshing. I tried to set it to refresh it every 24 hours by specifying the following:
REFRESH COMPLETE START WITH sysdate+0 NEXT sysdate+1
The database modified it to be:
REFRESH COMPLETE ON DEMAND START WITH sysdate+0 NEXT sysdate+1
I'm not sure why this materialized view is not being refreshed. Here is the full DDL for the view:

Answer 1

I had quite similar problem/question. And un/fortunately answered it by myself, nobody was interested in help :)
For the first sight: two "concurrent" statements have been used: ON DEMAND and START WITH. I wonder why database changed good code.
Look into my topic: How to recreate materialized view and maintain priviledges?
Look also here: Re: error on "CREATE MATERIALIZED VIEW" for more details.
HTH, Rev
