Difference between sum of values for recent date and 2nd most recent date.
While going through the Microsoft Power BI Community, I saw a post where a fellow member was asking for a solution to the problem in getting the difference between the sum of values for the most recent date and Just the previous date.
I worked to find a solution for the problem and found that the solution was interesting for people who would like to play with DAX.
Problem Statement
Solution
Step 1: Prepare the dummy table
Current sales sum =
VAR MAX_DATE =
MAX ( ‘Table'[Date] )
RETURN
CALCULATE ( SUM ( ‘Table'[Sales] ), ‘Table'[Date] = MAX_DATE )
Step 3: Write DAX measure for getting the 2nd most recent date so that we can create another measure for finding the sum of value for the 2nd most recent date.
2nd most recent date =
VAR current_date =
MAX ( ‘Table'[Date] )
RETURN
CALCULATE ( MAX ( ‘Table'[Date] ), ‘Table'[Date] < current_date )
Step 4: Write the DAX measure for finding the sum of values for the 2nd most recent date.
2nd most recent date Sales =
VAR previous_date_just = [2nd most recent date]
RETURN
CALCULATE ( SUM ( ‘Table'[Sales] ), ‘Table'[Date] = previous_date_just )
Step 5: Write DAX Measure for finding the difference between sum of values corresponding to most recent date and 2nd most recent date.
Difference =
[Current sales sum] – [2nd most recent date Sales]
