cancel slicer dates

Step 1) Helper: Selected date (or today) and the 7-day window

_Selected Date =
COALESCE ( SELECTEDVALUE ( calendar1[Fecha] ), TODAY() )

_In Window =
VAR Cutoff = [_Selected Date]
VAR StartD = Cutoff - 7
VAR EndD   = Cutoff - 1
VAR ThisD  = MAX ( calendar1[Fecha] )
RETURN
IF ( ThisD >= StartD && ThisD <= EndD, 1, 0 )

Put "_In Window" in the visual-level filters and keep only = 1. This makes the table show only the 7 days prior.

Step 2) Count by fecha_radicacion (calendar1)

Orders (Radicacion) =
VAR Cutoff = [_Selected Date]
VAR StartD = Cutoff - 7
VAR EndD   = Cutoff - 1
RETURN
CALCULATE (
    COUNTROWS ( Fact ),
    REMOVEFILTERS ( calendar1[Fecha] ),
    DATESBETWEEN ( calendar1[Fecha], StartD, EndD )
)

Step 3) Count by fecha_solucion (calendar2) without being restricted by filing date

Orders (Solucion) =
VAR DatesOnAxis = VALUES ( calendar1[Fecha] )
RETURN
CALCULATE (
    COUNTROWS ( Fact ),
    REMOVEFILTERS ( calendar1 ),
    TREATAS ( DatesOnAxis, calendar2[Fecha] )
)
