Calculate Sum of Latest Date Instead of Zero Values

[MickyG]

`           I am trying to calculate the number of children enrolled in each campus per date, but I would like for the latest value to roll over until there is new enrollment data to be calculated. For example, campus 1 has enrollment data for 9/29 & 9/30, but not for 10/1. Instead of a zero value, I would like to write a measure that would calculate the enrollment sum for the latest date available. So the values for 10/1 & 10/2 would be 728 until 10/3, where the latest value would be 729.

            I have included the matrix with the results I am getting for the enrollment data and the DAX measure. The matrix rows use the campus from the campus table and the dates from the dates table. The values [Enrollment] is the measure I have attached. All the examples I’ve seen online use only one table, but I am using the dates table so it's been difficult getting an exact example.

NOTE: Also I just want to make it clear I am not asking for a cumulative or rolling sum. Just the sum of the latest date where there is enrollment data.

Hi, @MickyG 

You can try the following methods.
Column:

Column = IF([Value]=0,BLANK(),[Value])

Column2 = CALCULATE (
LASTNONBLANK('Enrollment Data'[Attendance Date],1),
FILTER (
'Enrollment Data' ,
[Attendance Date] <= EARLIER ( 'Enrollment Data'[Attendance Date] )
&&[Column]<>BLANK()))

Column 3 = 
CALCULATE(MAX('Enrollment Data'[Value]),FILTER('Enrollment Data',[Attendance Date]=EARLIER('Enrollment Data'[Column2])))

Result:

Is this the result you expect?

Hey @MickyG ,

try to use the DAX function LASTNONBLANKVALUE: LASTNONBLANKVALUE – DAX Guide

Hopefully, this provides an idea on how to solve this.

I previously looked into this and I'm getting the same result. This is the formula I'm using. Not sure what I'm doing incorrectly?
