IF Issue in Measure

[Trist]

Hello Everybody, how are you? 

ı have question about writing a row context dax in a ıf clause . 

ı want to wrıte this query(*1) ınsıde of this query(*2). how to do that do u think?

*1:  

IF    A[X]="H"

THEN A[Y]*A[Z]*(-1)
ELSE IF A[X]="S"

THEN A[Y]*A[Z]
ELSE 0

-- A= TABLE NAME. X,Y,Z COLUMN NAME.

NOTE: I TRYED SWITCH FX BUT IT DOESNT WORKED.

*2: 

Values =

IF( ISBLANK( [Day] ), BLANK(), ---HERE İS GONNA BE SUM OF FORMULA(*1) ---- ))

-- Values is measure. 

Thanks,

Hello @Trist 
You can try this
Measure 1 =
IF (
ISBLANK ( [Day] ),
BLANK (),
IF ( A[X] = "H", A[Y] * A[Z] * ( -1 ), IF ( A[X,] = "S", A[Y] * A[Z], 0 ) )
)

SWITCH will work. You shouldn't name your measure VALUES - that is a function in DAX. Call it something else. 

New Measure =
IF(
    ISBLANK( [Day] ),
    BLANK(),
    SWITCH(
        TRUE(),
        A[X] = "H",
            A[Y] * A[Z] * ( -1 ),
        A[X,] = "S",
            A[Y] * A[Z],
        0
    )
)
