Ignore blank dates

[Syndicate_Admin]

Best regards.

I seek to get the value of the last 3 months from my sales table, my table goes:
Table date: January 2022 to December 2023
Sales table with values: Sales from January 2022 to date
I use the following measure only that it takes the last months of the table (Sep 2023, Oct 2023, Nov 2023, Dec 2023) and gives me zero(0) because I have no values yet, I need to get the values of the dates with data.

last n months =

where maxfecha= CALCULATE(.MAX(DATE[DATE]), ALL( DATE))

where minfecha= DATE(YEAR(maxfecha), MONTH(maxfecha)-7, 1)

where result=

CALCULATE(

SALES[SALES$],

FILTER(

DATE,

DATE[DATE] >= minfecha && DATE[DATE] <= maxfecha

)

)

return

result

They can help me skip worthless dates.

Hi @Syndicate_Admin ,

Because you do not provide sample data, so i could only give the solution according to your descriptions.

Please try below dax formula:

Measure =
VAR max_date =
    MAXX ( Sales, Sales[Date] )
VAR tmp =
    FILTER ( ALL ( Sales ), DATEDIFF ( Sales[Date], max_date, MONTH ) <= 3 )
RETURN
    SUMX ( tmp, Sales[SAles$] )
