Filtering a table similar to a where clause from SQL

[Anonymous]

Hi Community!

I am fairly new in DAX and I would like to ask for your help if there is way to convert this SQL query into DAX. I have 1 fact table in which I need to get the total amount of sales and 2 tables where this filters should be applied. is there a workaround with this query without the use of a date table?

SQL Query:

Period_ID between select period_ID from WeekTable where Week_ID =(select week_ID from DayTable where day_date =
(select DATEADD(Day, -120, CAST(GETDATE() AS DATE))))) and (select distinct period_ID from DayTable where day_date = CAST(GETDATE() AS DATE))

Here is the DAX that I have in mind, however, I'm encountering an error of "A function 'FILTER' has been used in a True/False expression that is used as a table filter expression. This is not allowed.". Are there a more appropriate DAX function to use in filtering, and should I use a calculated column or table, or this may be done with a single measure?

DAX:

2_test =

CALCULATE(

    SUM(SALES[Sales_Amount]),

        SALES[PERIOD_ID] = (FILTER(WeekTable, WeekTable[Week_ID] = FILTER(DayTable, DayTable[Day_date] = TODAY() - 120)

Looking forward for your suggestions. Thank you very much!

@Anonymous , the sql code is not complete

if you data for last 120 days based on today

measure =

var _min = TODAY() -120
var _max = today()
return CALCULATE([Net], FILTER('Date','Date'[Date] >=_min && 'Date'[Date] <= _max))

You need few week based on today

Weeks Today =
var _min = today() -WEEKDAY(today() ,2) +1 - 7*12 //12 weeks
var _max =today() -WEEKDAY(today() ,2) +7
return CALCULATE([Net], FILTER('Date','Date'[Date] >=_min && 'Date'[Date] <= _max))

If this does not help
Can you share sample data and sample output in table format? Or a sample pbix after removing sensitive data.
