Help with Month over month in specific format

[Anonymous]

I have report I need to build but layout requested is to have month over month aggregated over 3 month period.   How could i do this in PBI?   With matrix, the groupings and subtotals automatically get incorporated into each column group.

see below example of how i need it

Hi, @Anonymous ;

Base on my understand , you could have two ways to achieve it, as follows:

Method1:

1. create a Auxiliary table（Table2）

Table2 = 
var _a= SUMMARIZE('Table','Table'[cate],'Table'[date],"month",FORMAT('Table'[date],"Mmm"))
var _b=SUMMARIZE('Table','Table'[cate],"1",BLANK(),"month","MOM%")
return UNION(_a,_b)

2.create a measure2, 

Measure 2 =
VAR _PER=CALCULATE(SUM('Table'[value]),FILTER(ALLEXCEPT('Table','Table'[client]) ,[cate]=MAX('Table2'[cate])))/CALCULATE(SUM('Table'[value]),ALL('Table2'))
VAR _B= IF(MAX('Table2'[month])="MOM%",FORMAT(_PER,"0%"), CALCULATE(SUM('Table'[value]),FILTER('Table',[cate]=MAX('Table2'[cate])&&[date]=MAX('Table2'[date]))))
RETURN IF(ISFILTERED('Table2'[month]), _B,SUM('Table'[value]))

The final output is shown below:

Method2:

1. add three rows in power query .

2.create a measure1

Measure1 =
VAR _mom =
    CALCULATE (
        SUM ( 'another'[value] ),
        ALLEXCEPT ( 'another', 'another'[client], 'another'[cate] ))
RETURN
    IF (
        ISFILTERED ( 'another'[date] ),
        IF (
            MAX ( 'another'[date] ) = "MOM%",
            FORMAT (_mom/ CALCULATE ( SUM ( 'another'[value] ),ALLEXCEPT ( 'another', 'another'[client] )),"0%"),
            SUM ( 'another'[value] )),
        _mom)

The final output is shown below:

if not right, can you share me simple file after removing the sensitive information?

@Anonymous Hard to be sure but sounds like Rolling Months: https://community.powerbi.com/t5/Quick-Measures-Gallery/Rolling-Months/m-p/391499#M124

If not, Sorry, having trouble following, can you post sample data as text and expected output?
