I never used DAX and could not find a proper solution a surely easy question.
I have a measure with the total sales. In a table I also have a column with the sales of each shop. I need to discard some shops, but we have to compare with the total. If I filter some shops, the total chances, but I need to use the total even of the discarted shops.
So, how can I configure a column with the formule "previous column / Totals measure"?
