Time based Calculation groups - apply year to date to a yearly comparison - dax

Question

The workfile is available here
I wish to conduct time-based analysis on my datas.
For this purpose, I have created 2 calculation groups.
Year comparison that enables me to deal with relative yearly data :
N :=
VAR lv_MAX_YEAR =
[RELATIVE_MAX_YEAR] - 0
RETURN
CALCULATE (
SELECTEDMEASURE() ,
dim_CALENDAR[Year] = lv_MAX_YEAR
)
N-1 :=
VAR lv_MAX_YEAR =
[RELATIVE_MAX_YEAR] - 1
RETURN
CALCULATE (
SELECTEDMEASURE() ,
dim_CALENDAR[Year] = lv_MAX_YEAR
)
N/N-1 Evolution :=
VAR N = CALCULATE( SELECTEDMEASURE() , 'Year comparison'[Year comparison] = "N" )
VAR N_1 = CALCULATE( SELECTEDMEASURE() , 'Year comparison'[Year comparison] = "N-1" )
RETURN
N - N_1
Works fine for me with the expeced behaviour : N is by default the current year (max year in my calendar table), but if I filter on a given year, N becomes that one.
and Relative Period allows me to compare Sales by the number of passed day from the beginning of the year :
[MAX_YEAR_DAY] :=
VAR lv_MAX_YEAR =
CALCULATE (
MAX ( dim_CALENDAR[Year] ) ,
ALL ( dim_CALENDAR[Year] )
)
RETURN
CALCULATE (
MAX ( dim_CALENDAR[Year_day] ) ,
dim_CALENDAR[Year] = lv_MAX_YEAR
)
Year To Max Year_day :=
VAR lv_MAX_YEAR_DAY =
[MAX_YEAR_DAY]
RETURN
CALCULATE (
SELECTEDMEASURE () ,
dim_CALENDAR[YEAR_DAY] <= lv_MAX_YEAR_DAY
)
So far it's a partial success :
my grand totals seem correct ;
but my monthly details don't ;
and my yearly comparison gets busted when it's activated.
How can I use both calculation groups simultaneously?
