How to multiply a measure from table 1 to table 2 at the same aggregation.

[fast_rabbit852]

I have two tables as below:

1) Table A 

I want to build a measure which is a ratio of Day Of Week Occurance by Location/Total occurance of Day of Week. This measure should be able to change based on the date range selected in the slicer. Example: For location A there are 2 rows for Sunday out of total of five Sundays. 2/5 or 40%  is what I want the measure to show, if the date range is narrowed to 07/20-07/22 I want for location A and Sunday to be 1/3 or 33.33%.

2) Table B

Now I want to multiply the result of measure from table A to Table B by doing an Average of Column "Yes" by Day of Week & Location. So For location A & Sunday it should be 72*0.4=28.

Hi @fast_rabbit852,

Thank you for reaching out to the Microsoft fabric community forum. Also, thanks to @MohamedFowzan1, for his inputs on this thread. I reproduced the scenario, and it worked on my end. I used my sample data and successfully implemented it.

I am also including .pbix file for your better understanding, please have a look into it:

Hi @fast_rabbit852 

Build ratio measure for table A

A - DOW Ratio = 

DIVIDE(

    COUNTROWS(TableA),

    CALCULATE(

        COUNTROWS(TableA),

        REMOVEFILTERS(TableA[Location])

    )

Compute Average "Yes" in Table B

B - Average Yes = AVERAGE(TableB[Yes])

Combined Measure (Multiply the Two)

Result = 

VAR RatioA = 

    CALCULATE(

        DIVIDE(

            COUNTROWS(TableA),

            CALCULATE(

                COUNTROWS(TableA),

                REMOVEFILTERS(TableA[Location])

            )

        ),

        -- Optional: add a filter if a relationship is missing:

        FILTER(TableA, TableA[Location] = SELECTEDVALUE(TableB[Location]) && TableA[DayOfWeek] = SELECTEDVALUE(TableB[DayOfWeek]))

    )

VAR AvgYesB = 

    CALCULATE(

        AVERAGE(TableB[Yes])

    )

RETURN

    RatioA * AvgYesB
