Avoid Admins activating Logic files

Hello All,

We are on BPC MS 7.5 platform, we are having issues like logic files are activated without a proper track or .LGF and .LGX files are having different timestamp.

So, the questions, how can I avoid uses or admin team members from activating or creating logic files... they should be able to add/modify/process dimension members, but not logic files.

All our admin members are having all tasks profiles, I think segregating tasks profile to seperate tasks for a group of admin users will solve this problem.

Thanks
