Countrows/calculate/sum rows in DAX - powerbi

Question

I am fairly new with Power BI and DAX and I'm stuck. I'll try to explain the current situation and what I want to become my output. I've tried a lot of meaures with distinctcount, calculate, you name it, I did it. But can't find the right solution.
We've got 4 columns: Date, Employee_ID, Sick, %FTE. Every row records if an employee was sick on that date. Blank is not sick and Y = sick.
I would like to create a measure where it counts the %FTE just once when an employee is sick in a particular week, month or year.
So the output of January should be 2,13 (0,8 + 0,33 + 1) and in February 1,8 (0,8 + 1).

Answer 1

You would need two additional columns in the dataset as following
Once you have that, you can use the following measures to reach the goal
Measure8 =
VAR _1 =
IF (
MAX ( 'fact'[sick] ) <> BLANK (),
RANKX (
FILTER (
ALL ( 'fact' ),
'fact'[emp_id] = MAX ( 'fact'[emp_id] )
&& 'fact'[Year] = MAX ( 'fact'[Year] )
&& 'fact'[Month] = MAX ( 'fact'[Month] )
&& 'fact'[sick] = "Y"
),
CALCULATE ( MAX ( 'fact'[date] ) ),
,
ASC,
DENSE
)
)
VAR _2 =
IF ( _1 = 1, IF ( MAX ( 'fact'[sick] ) = "y", MAX ( 'fact'[%FTE] ) ) )
RETURN
_2
Measure9 =
IF (
HASONEVALUE ( 'date'[date] ),
[Measure8],
VAR _1 =
MAXX (
GROUPBY (
ADDCOLUMNS ( 'fact', "val", [Measure8] ),
[Year],
[Month],
"total", SUMX ( CURRENTGROUP (), [val] )
),
[total]
)
VAR _2 =
MAXX (
GROUPBY (
ADDCOLUMNS ( 'fact', "val", [Measure8] ),
[Year],
"total", SUMX ( CURRENTGROUP (), [val] )
),
[total]
)
VAR _3 =
IF ( ISINSCOPE ( 'fact'[Year] ), _2, _1 )
RETURN
_3
)
