When applying a template to a report, it’s often preferred to “peek” inside the template to see what it has to offer prior to applying it to your report; to “take it for a test drive”, as it were.
If you have a vast template library, and many templates are similarly named, it can be of great benefit to see a preview of what you will receive if applied. The Template Expert provides just such a preview.
For those who prefer to create their own templates, and possibly add them to the library, the preview feature may not display if certain prerequisites have not been satisfied.
