The Advanced Report Designer allows you to customize the appearance of your reports. For example, you can add graphics such as a company logo, change the color of parts of the report, add lines or boxes, rearrange fields, etc.
There are two Advanced Report Designers available:
The browser-based Advanced Report Designer is available within the report wizards.
The desktop-based Advanced Report Designer is a separate application you run on your desktop system.
The browser-based Advanced Report Designer has some limitations the desktop-based one doesn't have: it doesn't work with cross-tab or chart reports and it doesn't have as many options available. So, while the browser-based one is more convenient to use, there may be times when you need to use the desktop-based one.
