Create a cumulative count based on criteria

Hi AragakiSora ,

Please check that this calculated column meets your requirements:

Flag = 
VAR CurrentName = 'Table'[Name]
VAR CurrentDate = 'Table'[Last Update]
VAR CurrentID = 'Table'[ID]
VAR MinDateWithID = 
    CALCULATE(
        MIN('Table'[Last Update]),
        FILTER(
            'Table',
            'Table'[Name] = CurrentName &&
            NOT(ISBLANK('Table'[ID])) &&
            'Table'[Last Update] <= CurrentDate
        )
    )
RETURN
    IF(
        ISBLANK(CurrentID) && MinDateWithID > DATEADD('Table'[Last Update], -7, DAY),
        1,
        0
    )
