Filter Problems

[Anonymous]

I've made a formula to calculate 12 past week based on user selection

This is working without problems

the main problem is that if user select a period (week) the other visual are not affected and they dont show the correspoing period that was filtered 

i use this formula to calculate the past 12 weeks 

ASN_Selected =
var selecteddate_=
IF (
ISFILTERED (Dim_Period_Filter[Pep Week2]),
MAX(Dim_Period_Filter[Date])
)
var selectedateprevious = DATE(YEAR(selecteddate_),MONTH(selecteddate_),DAY(selecteddate_)-84)
RETURN
CALCULATE(ASN_Fact[ASN %],DATESBETWEEN(ASN_Fact[Date],Convert(selectedateprevious,string),convert(selecteddate_,STRING)))

and this one is used to show the max value from the filtered period (this should not be affected by the 12 past weeks), since this value is used on a Matrix and the 12 past week is used on a Sparkline

ASN_Label = 
var selecteddate_=
IF (
    ISINSCOPE( Dim_Period_Filter[Pep Week2]),
    MAX(Dim_Period_Filter[Date])
)
var selectedateprevious = DATE(YEAR(selecteddate_),MONTH(selecteddate_),DAY(selecteddate_))
RETURN
CALCULATE(ASN_Fact[ASN %],DATESBETWEEN(ASN_Fact[Date],Convert(selectedateprevious,string),convert(selecteddate_,STRING)))​

Hi @Anonymous ,

To filter out the past 12 weeks (48 days) based on the slicer selection, you need to calculate the max and min dates for those 12 weeks.

Sample data

Here's my solution.

1.Create a calendar table.

Calendar =
ADDCOLUMNS (
    CALENDAR ( DATE ( 2021, 1, 1 ), DATE ( 2021, 12, 31 ) ),
    "YearWeek",
        YEAR ( [Date] ) & " "
            & FORMAT ( WEEKNUM ( [Date], 2 ), "00" )
)

Note that there is no relationship between the two tables.

2.Create two measures to get the max and min dates.

MaxDate =
VAR _select =
    SELECTEDVALUE ( 'Calendar'[YearWeek] )
VAR _year =
    VALUE ( LEFT ( _select, 4 ) )
VAR _week =
    VALUE ( RIGHT ( _select, 2 ) )
RETURN
    MINX (
        FILTER (
            ALL ( 'Calendar' ),
            _year = YEAR ( [Date] )
                && _week = WEEKNUM ( [Date], 2 )
        ),
        [Date]
    )

MinDate = [MaxDate]-48

3.Now you can limit the dates of the main table based on the date range.

For example, create a measure to display the past 12 weeks of data for the week number selected by the slicer.

Measure = IF(MAX('Main Table'[Date])>=[MinDate]&&MAX('Main Table'[Date])<=[MaxDate],"Yes","No")

This is the sparkline showing 12 past week (based on user selection) 

Is user selects a period 

my matrix (thst use the second formula to calculate ASN) is not filtering
