How can we disable info area when we're opening query ??

Dear All,

It's regarding authorization in query designer.

I've already created roles .. So if user's opening the query, they can see their authorized query in roles group.

But ..

When they're opening the query, they also can search the query by info-area. When they search the query by info-area, they can see all query.

My question is:

1. How can we disable the feature to seek the report by info-area ??

2. Do you know what the authorization is for maintaining part ??

Regards,

Niel.
