Start of previous month formula

Hi community,

 

I have a table like the example below, were i am trying to compare the difference between 2 values across months.

 

I want to see if there is a decrease between the qty at the start of this month vs the start of last month.

 

EG In the below example, i want my formula to find the first day that there is data for the previous month, and compare this against the first day there is data for the next month. (This may not always be consistent)

 

Is this possible ?

Many thanks !

Hi thanks for the help - i have changed the data slightly so in my raw data i have a tag against each row that is the first value for the month.

I will add this as a filter on the page, and then i want to create 2 fields. Previous month QTY & This month QTY.

I want to show in a table these values across each month.

 

I this possible with the above method ?

 

Thanks !

//based on selecteddate or or today
previous months =
var _max = maxx(allselected('Date'), 'Date'[Date]) //or//Today()
return
calculate(sum(Table[QTY]), filter(all('Date'), 'Date'[Date] = eomonth(_max,-2)+1)

 


//based on selecteddate or or today
next months =
var _max = maxx(allselected('Date'), 'Date'[Date]) //or//Today()
return
calculate(sum(Table[QTY]), filter(all('Date'), 'Date'[Date] = eomonth(_max,0)+1)
