Using the code sent by Michal, I tested different formulas and now it works, I added the line "ALLSELECTED('Append')" followed by the line "PARALLELPERIOD('Append'[DATE_REFERENCE], -1, QUARTER)"

This line allows me to select all the values, even those that were previously filtered and not retrieved by "PARALLELPERIOD"

Here is the code

CalculateMeasure = 
VAR CurrentValue = SUM('Append'[Value])
VAR CurrentSale = SUM('Append'[Sale])
VAR PreviousQuarterValue = 
    CALCULATE(
        SUM('Append'[Value]),
        ALLSELECTED('Append'),
        PARALLELPERIOD('Append'[DATE_REFERENCE], -1, QUARTER)
    )
RETURN
    IF (
        CurrentValue <> 0,
        CurrentValue - PreviousQuarterValue,
        IF (
            CurrentValue = 0,
            CurrentSale - PreviousQuarterValue,
            BLANK()
        )
    )
