Avoid Slicer not filter

[amarsale85]

Hi Experts,

I am trying to get a "count of Tasks" for Previous Period (PP). So for example, if the date filter is from 2020-03-01 to 2020-04-02, then difference between from and to dates = 32 days, so the previous period would be calculated as

From Date filter for PP : (From date=2020-03-01) - 1 - 32 days = 2020-01-28 

To Date filter for PP : (From date=2020-03-01) - 1 day = 2020-02-29

This measure is sliced by Location attribute to view number of tasks in PP by location

Relation in Model : DimDate <---> FactTask <----> DimLocation

Fact Data:

FactKey TaskID LocationID DateKey

1           1           1                20200302      

2           2           2                20200227

3           3           1                20200125

4           4           2                20200220

5           5           1                20200302

As a 1st step, I used FIRSTDATE() function to get "from date" as "2020-03-01" but rather i get firstdate for that location,

So for Location ID = 1 i get FirstDate as "2020-01-25" and for Location ID = 2 i get FirstDate as "2020-02-20" which isn't what i want. This leads to incorrect values. The issue is if i use FirstDate/Min function to get the "From Date" from date filter its getting sliced by location and i am getting wrong date.

I am using below dax formula:

=CALCULATE([Count of TaskID],DATESBETWEEN(DimDate[Date], DATEADD(PREVIOUSDAY(FIRSTDATE(DimDate[Date])),-1*(DATEDIFF(FIRSTDATE( DimDate[Date] ), LASTDATE(DimDate[Date] ), DAY )),DAY),PREVIOUSDAY(FIRSTDATE(DimDate[Date]))))

Thanks,

Amar

@amarsale85 I don't know how you are doing it, assuming you are using date table where you selected the range and this is what I will do for PP

PP = 
VAR __minDate = MIN ( DateTable[Date] )
VAR __maxDate = MAX ( DateTable[Date] )
VAR __numberofDays = DATEDIFF ( __minDate, __maxDate, DAY )
VAR __ppStartDate = __minDate - _numberofDays - 1
VAR __ppEndDate = __minDate - 1
RETURN
CALCULATE ( SUM ( DataTable[Column] ), DATESTBETWEEN ( DateTable[Date], __ppStartDate, __ppEndDate )
)

I would ❤ Kudos if my solution helped. 👉 If you can spend time posting the question, you can also make efforts to give Kudos whoever helped to solve your problem. It is a token of appreciation!

Thank you for the Answer @parry2k but i am 100% sure it cannot resolved in Power BI using dax measure as it was a model design issue which resolved this issue thankfully after wasting 10 hours of my time.

This can be marked as resolved.

I tried by changing the Filter direction from DimDate to Fact from "Both ways" to only "one way" and it worked. I also recently found this link: https://community.powerbi.com/t5/Desktop/Show-items-with-no-data-doesn-t-work-for-dates/td-p/863715

where the same thing was done. 

This works for that issue but I had to drop the relation between DimDate to Fact to prevent date from filtering attributes but it should filter measures.,

Thank you,

Amar
