I am updating this post because I didn't find something to solve this problem yet.
How can I disable button "Manage" in Power Pivot tab in excel 2010. The problem is that I want the users to refresh a power pivot and have all the good stuff (analytics etc.) but I also want to hide my work in the database of the power pivot. So disabling the "Manage" button of the data base with something like password I believe could be a solution. Can I disable/enable "Manage" button with Vba code? Any ideas?
