Incremento del valor de fecha anterior

Hola

no puede encontrar una solución para la caliculción de incrementos en función de pocas condiciones.

Ejemplo de tabla actual en mi Power Query:

FechaPersonaRendimiento
4.4.2020A10
4.4.2020B12
4.4.2020C8
4.4.2020D15
5.4.2020A12
5.4.2020B16
5.4.2020C10
5.4.2020D5
6.4.2020A9
6.4.2020B8
6.4.2020C11
6.4.2020D7
7.4.2020A6
7.4.2020B4
7.4.2020C20
7.4.2020D11


Solución esperada:

Necesito calcular el incremento de la columna "rendimiento" basado en el valor de fecha anterior incluir la evaluación de la columna "persona":

fecha 4.4.2020 para persona - A hay rendimiento 10

fecha 5.4.2020 para la persona - A hay rendimiento 12

entonces el incremento es de 2

FechaPersonaRendimientoIncremento
4.4.2020A100
4.4.2020B120
4.4.2020C80
4.4.2020D150
5.4.2020A122
5.4.2020B164
5.4.2020C102
5.4.2020D5-10
6.4.2020A9-3
6.4.2020B8-8
6.4.2020C111
6.4.2020D72
7.4.2020A6-3
7.4.2020B4-4
7.4.2020C209
7.4.2020D114

Thx para una ayuda.

Así que básicamente, como en el artículo al que se hace referencia, algo así como:

Increment Column =
  VAR __Current = [performance]
  VAR __PreviousDate = MAXX(FILTER('Table',[person] = EARLIER([person]) && [date] < EARLIER([date])),[date])
  VAR __Previous = MAXX(FILTER('Table',[person] = EARLIER([person]) && [date] = __PreviousDate),[performance])
RETURN
  __Current - __Previous

@jeyare ,

Trate como


diff ?
var _last á maxx(filter(Table,table[person]-earlier(table[person]) && table[Date] á anterior(table[Date])-1),table[performance])
devolución
if(isblank(_last),0,performance-_last)

thx, parece estar bien hasta la primera fila, cuando recibo un error:

No se puede determinar el valor de 'performance'. O bien 'performance' no existe o no hay ninguna fila actual para una columna denominada 'Tperformance'.

Entonces IF necesita estar allí, pero no está seguro de dónde

mi respuesta fue para @Greg_Deckler

Hmm, véase PBIX adjunto. No puedo decir lo que salió mal, pero el PBIX parece funcionar bien.
