PREVIOUSMONTH with wrong total and subtotal

[Anonymous]

Hello,

I am trying to calculate the previous month value of transactions with the following code :

Transactions PM = 
VAR LastDayAvailable =
    CALCULATE (
        MAX ( TKT[TKT_DATE] ),
        ALL ( TKT )
    )
VAR CurrentDates =
    FILTER (
        VALUES ( Date[Date] ),
        Date[Date] <= LastDayAvailable
    )
VAR Result =
    CALCULATE (
        [Number of transactions],
        PREVIOUSMONTH ( CurrentDates )
    )
RETURN Result

The results are good concerning each indivudual months. However the totals are wrong as seen on screenshot.

Can you please help me on that ?

@Anonymous , if you have date you can use time intelligence with date table

MTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD('Date'[Date]))
last MTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(dateadd('Date'[Date],-1,MONTH)))
previous month value =  CALCULATE(sum('table'[total hours value]),previousmonth('Date'[Date]))

To get the best of the time intelligence function. Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s. Refer :

Dear @amitchandak, 

Thanks for the reply but your solution does not work for me.

As I said, my problem is with the totals and subtotals.

@Anonymous , because the previous month  is in context so grand total will on last month

try like

sumx(summarize(Table, Table[year], Table[Month],"_1",[Transactions PM]),[_1])

@Anonymous - This looks like a measure totals problem. Very common. See my post about it here: https://community.powerbi.com/t5/DAX-Commands-and-Tips/Dealing-with-Measure-Totals/td-p/63376

Also, this Quick Measure, Measure Totals, The Final Word should get you what you need:

Dear @Greg_Deckler,

Thank you very much, you put me on the right track.

Just add the following code in the return :

RETURN IF(HASONEVALUE(Date[Date_id_mois]);Result)

It works great !
