How can I do commodity structure visible for all user in RSS?

I have a problem with commodity structure, i define the items list (type S) in P40500-fig 1, on my user(SYSADMIN) that's all ok, but for another users (user's role has access to aplications P40500, P40500s, P4101, P4102, P41026, P41024) the list is not visible-fig 2. For non-stock items (type N, J)-fig 3, the list is visible for all users- fig 4. What apllications to have add in role for to do the list visible or which is the problem?
