Create a column that contains the previous average of days

[ Edited ]

I have 2 tables.
The First with the calendar of the year (Calendario)
The Second with daily assistance. (Asistencia)
As shown below

I need to add a column to the attendance table that shows the previous average of the last 3 weeks (excluding the day) according to the day as for example

I did this Dax formula but only the attendance of the day and I do not know how to add the filter per day

 

Prom Anterior Diario = CALCULATE(AVERAGEX(Asistencia;Asistencia[Asistencia]);DATESBETWEEN(Calendario[Fecha];DATEADD(Asistencia[Fecha];-21;DAY);DATEADD(ResumenDiario[Fecha];-1;DAY))

Hi @jcabeza,

 

Please use the below DAX

Prom sAnterior Diario = CALCULATE(AVERAGEX(Asistencia,Asistencia[Asistencia]),DATESBETWEEN(Calendario[Fecha],DATEADD(Asistencia[Fecha],-21,DAY),DATEADD(Asistencia[Fecha],-1,DAY)))

I have got the below result from this DAX

Regards,

Affan
