Percentage difference between dynamic dates

Good morning, I can’t find a solution to this problem. I have this calculation:

and everything is fine up to that point. The issue arises when I try to add a column that subtracts the current month from the previous month, as shown in the image.

I have tried all table calculations, but I believe the problem is due to aggregations. I hope you can help me.

Thank you.

Hello @SolSar62 hope this message finds you well!!

have you ever tried the difference formula? when I saw you problem, looks like this could be a way:

difference

Calculates difference of the measure with forward or backward lookup partitioned and sorted by specified attributes.

SYNTAX

difference(aggregated measure, [sort attribute ASC/DESC, ...], lookup index, [partition by attribute, ...])

please, tell me if it’s work for you

Yes, it worked, Thanks! I had to add a filter that considers both the current and the previous date.
I ended up with one column showing the correct calculation and another one that is empty.

When I try to hide the empty column, all the results disappear.
