AFAIK, if dbc and backup are not possible, then I can think of Unity Director, if you have system1 and System2. Just my thought.
but i know that we can get the latest(current) view definition from dbc.tables.
I was wondering if there is any other table which can give old view definition..
Unfortunately, we do not maitain the version of views.. We do have backups..I was trying to find out if there is any other way !!
Thanks for your replies !!!
