Cognos object security

I am attempting to setup object security on certain columns in our cognos model. I have set the security on a given column in a query subject. I then use those query subjects in namespaces multiple times. The security I setup in my query subject doesn’t carry through to the namespace. It appears that i have to set the column security in each namespace that i use that query subject item? Is that correct or am i missing something?

That is correct. Object security can’t propagate between namespaces, unless you’re using shortcuts.
