New custom namespace creation for non modifiable custom queries

Hello all,

I would like to create a group of custom queries in my SAP BI 7.30 system that will not be modifiable by users. I am thinking of creating a new

custom namespace (ZBO for example) and create those queries under that namespace. Is there a setting anywhere where I can specify

that any query created under such namespace (ZBO and ideally anything under that like ZBOA, ZBOB, in general ZBO*) will not be modifiable?

Also, is it possible to do the same (create other non modifiable objects (not only queries)) under the same namespace ?

Many thanks

Andreas
