Overlapping Data

Hi keylian031987 ,

Please try this column:

Column = 
VAR _start_date1 = 'Table'[Start Date]
VAR _employee = 'Table'[Employee Backup]
VAR _start_date2 =
    CALCULATE (
        MIN ( 'Table'[Start Date] ),
        FILTER ( ALL ( 'Table' ), 'Table'[Employee Name] = _employee )
    )
VAR _end_date1 = 'Table'[End Date]
VAR _end_date2 =
    CALCULATE (
        MAX ( 'Table'[End Date] ),
        FILTER ( ALL ( 'Table' ), 'Table'[Employee Name] = _employee )
    )
VAR _result =
    IF (
        OR (
            AND ( _start_date2 >= _start_date1, _start_date2 <= _end_date1 ),
            AND ( _end_date2 >= _start_date1, _end_date2 <= _end_date1 )
        ),
        "Overlapping",
        "Non Overlapping"
    )
RETURN
    _result
