Hi @GiuPowerBi ,

Based on the information you have provided, you can follow the steps below:

1.Add new column.

Key =
IF (
    'Table'[Type] = "Employee"
        && 'Table'[Date] >= MAX ( 'Table2'[Lower Date] )
        && 'Table'[Date] <= MAX ( 'Table2'[Upper Date] ),
    1,
    IF (
        'Table'[Type] = "Freelance"
            && 'Table'[Date] >= MAX ( 'Table2'[Lower Date] )
            && 'Table'[Date] <= MAX ( 'Table2'[Upper Date] ),
        2,
        IF (
            'Table'[Type] = "Employee"
                && 'Table'[Date] >= MIN ( 'Table2'[Lower Date] )
                && 'Table'[Date] <= MIN ( 'Table2'[Upper Date] ),
            3,

Hi @GiuPowerBi 

What is the logic to declare the Foreigh key in your last screenshot

[GiuPowerBi]

Hello,

logic is Date should be within other table LowerDate and Upper Date and Type should match.

Thank you
