I'm having some issues calculating the percentage between two cumulative sums (with a custom formula).
In my previous question (link: Cumulative SUM in Metabase) I have asked a tip to calculate the Cumulative Sum without losing the multiple filter feature.
In the picture below you can see two tables.
In the first one (left-side) I have the total amout for month and the percentage between 'Cumulative sum of Balance_2_Years' (year 2022) and 'Cumulative sum of Balance_Last_Year' (year 2023). It is correct.
I would like to have the same result for the right-side table, which contains the total cumulative amount for the last two years.
The formula that I used seems correct (I have used the same for the non cumulative table in the left, but using the SUM() function, and not CUMULATIVE_SUM()). As you can see, it doesn't work.
