Can we Hide Measure Folders from a Read Only Session?

Question

Hi ,
I have implemented security on my workspace by scoping the dimensions and hiding the cubes.It worked.
For hiding measure folders, i did similar to hiding of cubes, but it did not work. It threw an error message :
ERROR: (ORA-34706) ACCOUNT_BW.MEASUREFOLDER is not a valid XPRO_OLAP_NON_AGG.OLAP_NON_AGG!ALL_CUBES.
Iam cannot understand why the OLAP DML is checking a measurefolder in ALL_CUBES .
Can anyone help ?
Sample code of Hiding cubes is below.
Thanks,
Chakri

Actually, their should be an easier way - my brain wasn't in full gear yesterday.
Select the file/folder(s) you want to make aliases for and then hold down the command and option key at the same time. Now drag the files/folders to where you want the aliases to be, and hey presto!
Slightly easier than the method I mentioned earlier
