Calcular columna a medir

[Syndicate_Admin]

Hola

¿Cómo puedo convertir lo siguiente en una medida?

Column = 
COUNTROWS( (
    FILTER (
        schedule,
        schedule[start_date] <= EARLIER ( [Date] )
          //  && schedule[end_date] >= EARLIER ( [Date] ) && schedule[no. of attachments] <> 0
          && schedule[end_date] >= EARLIER ( [Date] ) && schedule[no. of attachments] > 0
          && schedule[type] = "Appointment"
    )
))

@pieduke88 Probar:

Column = 
  VAR __Date = MAX('Dates'[Date])
  VAR __Result = 
COUNTROWS(
    FILTER (
        ALLSELECTED(schedule),
        schedule[start_date] <= __Date
          && schedule[end_date] >= __Date && schedule[no. of attachments] > 0
          && schedule[type] = "Appointment"
    )
)
