How to match two unrelated dates tables using DAX ?

[Abhanshu97]

We have two tables - Table A and Table B

Table A contains the column of Employee ID(EID) and Date of Joining(DOJ).

Table B contains the column of Dates(Date) only.

There is no relationship between two tables.

Please suggest me how do I match the two tables such that if we select date slicer from Table B then it would change the data of Row card containing count of EID ?

I have tried using Lookupvalue but it didn't work.

Any help would be appreciated!!

Hi @Abhanshu97 

You can try to build a measure to calculate the count of Employee ID in Table A based on the filter of unrelated Date table.

Table A:

Date Table:

Date = CALENDARAUTO()

They are unrelated.

If you want to select dates directly in date slicer, try this measure.

Measure = 
VAR _SelectValue = VALUES('Date'[Date])
VAR _Count = CALCULATE(COUNT('Table A'[Employee ID]),FILTER(ALL('Table A'),'Table A'[Date] in _SelectValue))
RETURN
_Count

By default, no selection in date slicer, result should return to 8.

In silcer I select 2021/05/10 and 2021/07/05, result should return to 3.

If you want to filter Table A by between function in unrelated date slicer, try this measure.

Measure 2 = 
VAR _RangeStart = MIN('Date'[Date])
VAR _RangeEnd = MAX('Date'[Date])
VAR _Count = CALCULATE(COUNT('Table A'[Employee ID]),FILTER(ALL('Table A'),AND('Table A'[Date]>=_RangeStart,'Table A'[Date]<=_RangeEnd)))
RETURN
_Count

By default:

Range between 2021/05/10 and 2021/07/05:

Hi Abhanshu97

Make a relationship between the tables, join the Date[date] and Date of joininid columns. By doing this the slicer will change your row card

Best regards

Thanks Portrek!

But here the problem is that, we can't create the relationship between tables. I mean we only have to use DAX to match the tables.

Is that be possible to do so with DAX?

Without relationships I find it very difficult to get. Good luck !
