¿Cómo crear una columna calculada para restar el valor de fila anterior?

Hola

Necesito crear una columna calculada que resta el valor de fila actual del valor de fila anterior en función de la fecha y el nombre del cliente. Por ejemplo:

FechaValorClienteCalc_column (valor esperado)
01-04-2020100A
01-04-2020400B
01-04-2020500C
02-04-2020120A20
02-04-2020440B40
02-04-2020560C60

¡Gracias de antemano!

Calc_column = 
var _thisDate = Table[Date]
var _prevDate = CALCULATE(MAX(Table[Date]), ALLEXCEPT(Table, Table[Customer]), Table[Date] < _thisDate )

RETURN
Table[Value] - CALCULATE(MAX(Table[Value]), ALLEXCEPT(Table, Table[Customer]), Table[Date] = _prevDate )

Vea mi artículo sobre el tiempo medio entre el error (MTBF) que utiliza EARLIER: http://community.powerbi.com/t5/Community-Blog/Mean-Time-Between-Failure-MTBF-and-Power-BI/ba-p/3395...

Así que en tu caso, algo como:

Calc_column = 
  VAR __PreviousDate = MAXX(FILTER('Table',[Date] < EARLIER([Date]) && [Customer] = EARLIER([Customer])),[Date])
  VAR __PreviousValue = MAXX(FILTER('Table',[Date] = __PreviousDate) && [Customer] = EARLIER([Customer])),[Date])
RETURN
  [Value] - __PreviousValue

@ashrafkotb ,

Pruebe nuevas columnas como

Fecha máxima: maxx(filter(Table, table[Date]<earlier(Table[Date]) && table[Customer]-earlier(Table[Customer])),Table[Date])
diff - Table[value] - maxx(filter(Table, table[Date]-earlier(Table[max date]) && table[Customer]-earlier(Table[Customer])),Table[value])
