In the merchant panel you can find a lot of different reports and overviews. Each report has its own view settings (records per page, viewed and not viewed data types) which you can change.
If you want to change these settings, go to the required report and click the "Edit view" link in the right upper corner.
Then the 'Edit view' window appears where you can choose the desired type of data to be viewed.
For one report you can create more views which you can save under custom name. The Default viewmay not be changed, therefore you need to chose a custom name.
