Can't get the recent Date Values

Hello yve214. 

I was able to get this to work by creating a new table with the following DAX:

New table = 
ADDCOLUMNS(
    SUMMARIZE( 'Table', 'Table'[Emp_ID], 'Table'[Interval] ),
    "Effective Date", CALCULATE( MAX( 'Table'[Effective_Date] ) ),
    "Score", CALCULATE( MAX( 'Table'[Score] )),
    "ID", CALCULATE( MAX( 'Table'[ID] ) )
)

I created a .pbix file that you can download here.

Hi yve214. Ah, I think understand now. See if this works for you:

Count of Emp IDs =
CALCULATE (
    DISTINCTCOUNT ( 'Table'[Emp_ID] ),
    FILTER (
        'Table',
        VAR CurrentRowEmpID = 'Table'[Emp_ID]
        RETURN
            VAR IntervalZeroEffectiveDate =
                CALCULATE (
                    MIN ( 'Table'[Effective_Date] ),
                    ALL ( 'Table' ),
                    'Table'[Interval] = 0
                        && 'Table'[Emp_ID] = CurrentRowEmpID
                )
            RETURN
                'Table'[Interval] = 6
                    && 'Table'[Effective_Date] > IntervalZeroEffectiveDate
    )
)
