Transform Quarter Acumlated Values in Month Values

Hey, I tried it and I hope it will work for you:

- Add new column for ranking the data

Rank = RANKX(Filter(Table1, Table1[Category] = EARLIER(Table1[Category])), Table1[Date],,ASC,Dense)

- Add measure to get the value

Cummulative Total Unwind = 
var getPreviousRowRank = FIRSTNONBLANK(Table1[Rank],1) - 1
var getCurrentCategory = MAX(Table1[Category])
var getCurrentRowValue = MAX(Table1[Value])
var getPreviousRowValue = CALCULATE(MAX(Table1[Value]), Filter(ALLSELECTED(Table1), Table1[Category] = getCurrentCategory && Table1[Rank] = getPreviousRowRank))
return if(getPreviousRowValue = BLANK(), getCurrentRowValue, getCurrentRowValue - getPreviousRowValue)

Drop a table visual and add following to value:

- Date

- Category

- Cummulative Total Unwind (new measure)

And I guess you will get the data you are looking for

PS - Replace table name with your table name in DAX and also replace category with Cod and Value with Valor
