@deb_power123 ,

New columns

Month Year = FORMAT([Date],"mmm-yyyy")
Month Year sort = FORMAT([Date],"yyyymm")

Start Month date=  eomonth([Date],-1)+0

Start End date=  eomonth([Date],-1)+0

Month Type = Switch( True(),
eomonth([Date],0) = eomonth(Today(),-1),"Last Month" ,
eomonth([Date],0)= eomonth(Today(),0),"This Month" ,
Format([Date],"MMM-YYYY")
)

Hi @amitchandak It doesnt work, it doesnt fetch the output expected.You try the formula in pbix,it wont fetch the desired answer

[amitchandak]

@deb_power123 , Try a new table like

Table = ADDCOLUMNS( GENERATESERIES(1,12,1), "Year", year(Today()) , "Month Start Date", Date(Year(today()),[Value],1), "Month End Date", eomonth(Date(Year(today()),[Value],1),0) , "Month", format(Date(Year(today()),[Value],1),"MMMM"), "Previous Month Start Date", eomonth(Date(Year(today()),[Value],1),-2)+1, "Previous Month End Date", eomonth(Date(Year(today()),[Value],1),-1) , "Previous Month", format( eomonth(Date(Year(today()),[Value],1),-2)+1,"MMMM"))

Hi @amitchandak  If I want to show the data for 2019,2020 and 2021, what changes should I make to the above formula of yours?

At present it looks great but it calculates only for 2022 but I want to show 2019,2021 and 2020 data as well.Please suggest

@deb_power123 , Try like

Date2 = var _1 = ADDCOLUMNS( CALENDAR(date(2019,01,01), date(2021,12,31) ), "Year", year([date]) , "Month Start Date", eomonth([date],-1)+1, "Month End Date", eomonth([date],0), "Month", format([DAte],"MMMM"), "Previous Month Start Date", eomonth([date],-2)+1, "Previous Month End Date", eomonth([date],-1), "Previous Month", format(eomonth([date],-1),"MMMM"))
return SUMMARIZE(_1,[Year],[Month Start Date],[Month End Date],[Month],[Previous Month],[Previous Month Start Date],[Previous Month End Date])

if needed you can simply return _1 , no need of summarize
