By using Approval you are releasing or making your project public in a way. Once you are done reporting you will have to distribute your projects to end-clients. In addition to approval you would need to distribute or release your project to public.
As you can see you can distribute your reports in portions. This allows you use your portal for dual purposes: there will be section you set up to analyze the results, run crosses, create charts and then there will be sections that you deliver and distribute to clients. You simply tick the boxes of the sections you wish to distribute and then click the distribute reports button circled in red at the top-left of the screen.
