Counting new, old and returned items compared to the previous month

[daniel_morano]

Hi,

Is there a measure that will help me count new, old and returned items compared to the previous month?

Thank you in advance for any help 😉

Hi @daniel_morano ,

According to your description, here are my steps you can follow as a solution.

(1) My test data is the same as yours.

(2) We can create measures. 

new cars = 
var _a=SELECTCOLUMNS(FILTER(ALL('Table'),'Table'[DATE]=MAX('Table'[DATE])),"car",'Table'[CAR])
var _b=SELECTCOLUMNS(FILTER(ALL('Table'),INT('Table'[DATE])=INT(MAX('Table'[DATE]))-1),"car",'Table'[CAR])
return IF(INT(MAX('Table'[DATE]))=1,BLANK(),COUNTROWS(EXCEPT(_a,_b)))

returned cars = 
var _a=SELECTCOLUMNS(FILTER(ALL('Table'),'Table'[DATE]=MAX('Table'[DATE])),"car",'Table'[CAR])
var _b=SELECTCOLUMNS(FILTER(ALL('Table'),INT('Table'[DATE])=INT(MAX('Table'[DATE]))-1),"car",'Table'[CAR])
return COUNTROWS(EXCEPT(_b,_a))*-1

from previous month = 
var _a=SELECTCOLUMNS(FILTER(ALL('Table'),'Table'[DATE]=MAX('Table'[DATE])),"car",'Table'[CAR])
var _b=SELECTCOLUMNS(FILTER(ALL('Table'),INT('Table'[DATE])=INT(MAX('Table'[DATE]))-1),"car",'Table'[CAR])
return COUNTROWS(FILTER(_b,[car] in VALUES('Table'[CAR])))

(3) Then the result is as follows.
