    Materlized views

    I am creating a materlized view using OEM and when I check updatable checkbox It 's giving me an error that the view is too complicated.

    Is this issue with OEM or Oracle it self will not allow to create updatabale MV

    BTW i am using around 10 tables and 20 joins...

    any help is much appreciated

    OEM ought to give you the SQL -- try running it through SQL*Plus.

    I have to say though, it doesn't sound updateable.

    You can use dbms_mview.explain_mview procedure to explore functionality available with your materialized view query. Then you can play with your query to see what is changing. Make sure you don't violate any updatable mview requirements first.
