Doing percentage based on matrix row total and grouping row under it

[Shell64]

Hi I have the below problem, what I want to do is a measure that will update with slicer year/month being select by user an caluate the percentage each grouping is based on the month grand total. So in January there was a total of 140 and 80 in group 1 is 57% of that.

Thanks

January
Group 1	80	57%
Group 2	10	7%
Group 3	50	36%
February
Group 1	20	22%
Group 2	10	11%
Group 3	60	67%
March
Group 1	20	20%
Group 2	30	30%
Group 3	50	50%

Hi @Shell64 ,

You can create a measure as below to get it:

Measure =
VAR _year =
    SELECTEDVALUE ( 'Yourtable'[Date].[Year] )
VAR _monthno =
    SELECTEDVALUE ( 'Yourtable'[Date].[MonthNo] )
VAR _per =
    SUM ( 'Yourtable'[Value] )
VAR _group =
    CALCULATE (
        SUM ( 'Yourtable'[Value] ),
        FILTER (
            ALLSELECTED ( 'Yourtable' ),
            YEAR ( 'Yourtable'[Date] ) = _year
                && MONTH ( 'Yourtable'[Date] ) = _monthno
        )
    )
RETURN
    DIVIDE ( _per, _group )

If the above one can't help you get the expected result, please provide some raw data in your table (exclude sensitive data) with Text format and the relationship info between the tables. It would be helpful to find out the solution. You can refer the following link to share the required info:

And It is better if you can share a simplified pbix file. You can refer the following link to upload the file to the community. Thank you.

Read about REMOVEFILTERS.  Identify the total for each month by removing the group filter, and then divide the current value by that.
