I am trying to calculate the difference between units sold of some products on 2 consecutives weeks, the problem is that, at some weeks, my table has not any register of a sold, so, on the pivot table some lines are empty. Because of this, when I try to do the difference between then, it returns me a null value.
How can I calculate the difference between 2 columns in a pivot table when the column’s field is not a date data type?
I know there is a new functionality of table calculation that can help. The problem is it replaces the original aggregated metric with the table calculation function result and not adding it side by side.
