Transforming a Calculated Column into a Variable inside a Measure

[Anonymous]

I have the following Calculated column to figure out if which rows hold the latest versions of data

MaxDate = CALCULATE(MAX(ProjectsTable[Metric Date]),FILTER(ProjectsTable, Projects[Project Name]=EARLIER(ProjectsProject Name])))

Followed by this second calculated column which acts as a Flag 

LatestValue = If(ProjectTable[Metric Date] = ProjectTable[MaxDate], 1, 0)

Ultimately I'm trying to fit both of these inside a Measure as variables so the result can be dynamically filtered.

My problem is that the first column is a formula that doesn't work inside a measure. I'm getting errors with it. 

I tried playing around with it with something like this but to no avail

Var FilterDate = MAX(ProjectTable'[Metric Date])
Var LastUpdate = 
    CALCULATE(
    IF(MAX(Project Table[Metric Date]) <= FilterDate, 1, 0), VALUES(ProjectTable[Project Name]))

Note, the VALUES is because I need to filter latest date per Project name (different projects have different latest dates).

Thanks for any help!

To transform your calculated columns into a measure, you need to adjust your DAX code to handle row context within a measure. Here's how you can create a measure that identifies the latest version of data dynamically:

LatestValueMeasure = 
VAR MaxDatePerProject = 
    CALCULATE(
        MAX(ProjectsTable[Metric Date]),
        ALLEXCEPT(ProjectsTable, ProjectsTable[Project Name])
    )
RETURN
IF(
    MAX(ProjectsTable[Metric Date]) = MaxDatePerProject,
    1,
    0
)
