DAX: order of concatenated years

[adam_macs]

Hi, i have created a column that concatenates the assessment years that customers purchase and am trying to order the years from earliest year to latest year to help improve readability. I cannot seem to get the measure to work however? Any ideas on what I'm doing wrong?

CombinedAssessmentYears =
CONCATENATEX (
FILTER (
SUMMARIZE (
Finance_Sales,
Finance_Sales[CustomerName],
Finance_Sales[AcademicYear]
),
Finance_Sales[CustomerName] = EARLIER ( Customers[CustomerName] )
),
FORMAT ( Finance_Sales[AcademicYear], "YYYY" ),
", ")

Hi,

I am not sure how your Finance_Sales[AcademicYear] column looks like, but please try the below measure if it works.

CombinedAssessmentYears fix: =
CONCATENATEX (
    FILTER (
        SUMMARIZE (
            Finance_Sales,
            Finance_Sales[CustomerName],
            Finance_Sales[AcademicYear]
        ),
        Finance_Sales[CustomerName] = EARLIER ( Customers[CustomerName] )
    ),
    FORMAT ( Finance_Sales[AcademicYear], "YYYY" ),
    ", ",
    Finance_Sales[AcademicYear]
)
