Power Query Editor - Current Month Issue

[Rohini]

Reporting values during a current month requires pulling data pertaining to previous month i.e., during March, I need to extract data from the field [Feb 2020], in April, I need to extract data from the field [Mar 2020] and so on...

The following formula works in a query but not in power query - 

Current_Month = If (MONTH(TODAY())=3, [Feb 2020], (

            If (MONTH(TODAY())=4, [Mar 2020], (

If (MONTH(TODAY())=5, [Apr 2020], (

            If (MONTH(TODAY())=6, [May 2020], (

            If (MONTH(TODAY())=7, [Jun 2020], (

            If (MONTH(TODAY())=8, [Jul 2020], (

            If (MONTH(TODAY())=9, [Aug 2020], (

            If (MONTH(TODAY())=10, [Sep 2020], (

If (MONTH(TODAY())=11, [Oct 2020], (

If (MONTH(TODAY())=12, [Nov 2020], "999999999")))))))))))

))))))))

Can someone help me on how to extract the current month in power query editor?

This seems like DAX to me. Are looking for M code ?

https://docs.microsoft.com/en-us/powerquery-m/datetime-localnow

https://docs.microsoft.com/en-us/powerquery-m/date-month

https://docs.microsoft.com/en-us/powerquery-m/date-year

In DAX we could have used these with date calendar

MTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD('Date'[Date]))
last MTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(dateadd('Date'[Date],-1,MONTH)))
last MTD (complete) Sales =  CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(ENDOFMONTH(dateadd('Date'[Date],-1,MONTH))))
last year MTD (complete) Sales =  CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(ENDOFMONTH(dateadd('Date'[Date],-12,MONTH))))
last year MTD Sales =  CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(dateadd('Date'[Date],-12,MONTH)))
trailing Month= CALCULATE(SUM(Sales[Sales Amount]),dateadd('Date'[Date],-1,Month))

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 :

Hi @Rohini 

for Power Query use Date.Month(DateTime.LocalNow()) function

like

= if Date.Month(DateTime.LocalNow())=3 
then [Feb 2020]
else if Date.Month(DateTime.LocalNow())=4
then [Mar 2020]
else "999999999"
