Cumulative agregation Bar chart by period

[EJeronimo]

Hi, my first request was how to agregate the by chart by period and the solution was solved using the function below  provide by @BrunPierre .

Thank you.

====================================================================================

=Count(DISTINCT Aggr(If(MaxString(TOTAL <ITEM, [Month/Year]> DATE) = DATE, ITEM), ITEM, DATE, STATUS, [Month/Year]))

===========================================================

Now i need to cumulate this chart with base last condition, example:

For July/2023, the value should be:

Item "CPPRAA164308 - STEP 6 = 1"

and as the ITEM "CPPRAA163762 - STEP 7  = 1 " not appears in July should be get the last status from the Jun.

The final result for July shoud be:

CPPRAA16376 - STEP 5 = 1

CPPRAA164308 - STEP 6 = 1
