Split Values in Matrix by Different Rows (Which have the same type of data)

Hi lukexuereb ,

Try the following formula:

Measure = 
var _1 =
    CALCULATE(
        DISTINCTCOUNT('Table'[Column2]),
        FILTER(
            ALL('Table'),
            'Table'[Computation2ndReviewer] = MAX('Table'[Computation1stReviewer])
        )
    )
return 
    IF(
        ISFILTERED('Table'[Computation1stReviewer]),
        _1,
        [Comp 2nd Review]
    )

If the problem is still not resolved, please provide detailed error information or the expected result you expect. Let me know immediately, looking forward to your reply.

Best Regards,
