## Accumulated difference

I have a table like the one below which has the accumulated sales per month, I need to calculate the real value of the month considering that there are several companies that have different branches and that each one can belong to a different category.

Another option could be to create a column with the previous data and then perform the subtraction but I also have problems with that.

Consider that the real table has more companies, branches and goes from 1/2019 to 7/2023

I managed to do it this way. First create a column that has de previous value of sales.

Previous Sale =
VAR PreviousDate = DATEADD(BASE[Date], -1, MONTH
RETURN
IF(BASE[NUM_MONTH] = 1, 0,
SUMX(
FILTER(
'BASE',
'BASE'[DATE] = PreviousDate &&
BASE[Company] = EARLIER(BASE[Company]) &&
BASE[Branch] = EARLIER(BASE[Branch])
),
BASE[Sales]
)
)

Then I used a metric like the following.
Monthly Sales = SUM(BASE[Sales]) - SUM(BASE[Previous Sale])

That way i managed to get the monthly Sales by company and branches (Corredora = Company, Produccion = Sales, Produccion Mensual = Monthly Sales)
