Hi all,

I created a table in PRD like this:

First column is the current year, second is the previous.
Third is delta value created with a open formula.
The last one is delta percentage on previous year.

I used detail footer aggregation type SUM(running).

How can I combine aggregation type with delta percentage formula? Do I need to change behaviour and create a sum formula for each column?

Thank you.
