Once you've clicked on From a template report, you'll see a list of templates already loaded into Workbooks for you. For example, select Orders per Sales Exec, current and previous fiscal year.
The Reporting edit window appears. You should give you report a name and description. You can open the Details tab to see what's been included for you and check the Criteria tab to ensure that the template is focussed on the records you want to see.
Similarly, check the Summary View(s) to check what summaries are in place and that they meet your needs. You may need to refine any existing summaries and/or add new ones.
