Power bi dates diff conditional count

Hi, Compacted 

As you said, if your data sets are less than 50 days, you can count directly.

1. Calculated column

Count =
CALCULATE (
    COUNT ( 'Table'[ Code ] ),
    FILTER (
        'Table',
        'Table'[Employee ] = EARLIER ( 'Table'[Employee ] )
            && 'Table'[ Code ] = EARLIER ( 'Table'[ Code ] )
    )
)

 2. Measure

Measure =
CALCULATE (
    COUNT ( 'Table'[ Code ] ),
    FILTER (
        ALL ( 'Table' ),
        'Table'[Employee ] = MAX ( 'Table'[Employee ] )
            && 'Table'[ Code ] = MAX ( 'Table'[ Code ] )
    )
)
