Cumulative count in matrix filtered by date

[Syndicate_Admin]

Good afternoon, I would appreciate it very much if you can help me

The case is as follows:

I have two tables with data

The first table is:

from where we will take the categories for the matrix.

The second table is:

From this we will take those that are from July 1 and 2, 2022.

What I am looking for is to be able to make the following matrix:

What I need is for July 2, 2022 to add the value of the previous day plus the value of July 2.

Please note that from table 2 there is data from other dates which I do not want to bring to the matrix and that I would prefer to do it within the DAX formula and not with external filters.

One more doubt: if you wanted to bring the accumulated of the previous month, that is, the figure of 30/06/2022, it can be done and how it would be done???.

I thank you for the yuda.

Hi @Syndicate_Admin ,

You can do something like

cumulative sum =
CALCULATE (
    SUM ( table[value] ),
    FILTER (
        ALL ( table[date] ),
        table[date] <= MAX ( table[date] )
    ) //to create a sum of values where  date is less than or equal to the date in the current filter context
)

Thank you very much, I already tried the formula, but it does NOT work, for some reason I accumulate the figures since 2020 by category but does not filter me those of the month.
