Dear All,
I need to make a subtraction between two values on the same Column.
In my table I have the quantity of each ITEM at the end of the moth.
I need to add another column with the delta between two consecutive months:
quantity of February - quantity of Jannuary
quantity of March - quantity of Febrary
...
ITEM | date | Quantity | delta |
V32 | 31.01.2021 | 34 | |
V32 | 28.02.2021 | 77 | 43 |
V32 | 31.03.2021 | 30 | -47 |
M37 | 31.01.2021 | 46 | |
M37 | 28.02.2021 | 28 | -18 |
M37 | 31.03.2021 | 55 | 27 |
PowerQuery using M or Dax in PowerBI is both ok.
Thanks in advance
Paolo
Solved! Go to Solution.
You can create a calculate column using DAX by filtering with end of previous month.
If you don't want the blank, just use: Return [Quantity]-pre_eom_quantity

Hi, @paolomint
Please check the below picture and the sample pbix file's link down below for creating a new column.
Delta CC =
VAR currentitem = 'Table'[ITEM]
VAR rankingbydate =
RANKX ( FILTER ( 'Table', 'Table'[ITEM] = currentitem ), 'Table'[date],, ASC )
VAR previousquantity =
MAXX (
FILTER (
'Table',
'Table'[ITEM] = currentitem
&& RANKX ( FILTER ( 'Table', 'Table'[ITEM] = currentitem ), 'Table'[date],, ASC ) = rankingbydate - 1
),
'Table'[Quantity]
)
RETURN
IF ( NOT ISBLANK ( previousquantity ), 'Table'[Quantity] - previousquantity )
