Posted by Andrew Gould on 07 January 2021

Learn how to use the Previous function to compare values for the same day in the previous month and previous year. You'll learn how to change the scope of the Previous function to return values from different levels of parent groups and compare dates with the same period in a different month and year. The video includes some useful techniques for working with grouped tables, including how to create repeating and scrolling column headers, how to keep every row in a group on a single page and how to create document maps for quick navigation of a large report.
