How to flag status change

Hi deanbland ,

Please try the following formula:

Column = 
var PreDate = 
    MAXX(
        FILTER(
            'Table',
            'Table'[Date] < EARLIER('Table'[Date])
            && 'Table'[ID] = EARLIER('Table'[ID])
        ),
        'Table'[Date]
    )
var PD_Status = 
    CALCULATE(
        MAX('Table'[Status]),
        FILTER(
            'Table',
            'Table'[Date] = PreDate 
            && 'Table'[ID] = EARLIER('Table'[ID])
        )
    )
return 
    IF( PD_Status = BLANK() || PD_Status = 'Table'[Status], 0, 1 )

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.
