Formula Classification Help

[Mack1int]

Good Morning All,

 I am struggling with this formula it works for when the number of rows is 2 and the cumulated segmentation however when i put in the the extra count of 3 rows it doesn't classify them "A","B" and "C", instead it comes up with an error. Any help would be greatly appreciated.

Many Thanks

ABC Product =
VAR NoOfRows =
COUNTROWS (
CALCULATETABLE ( ABC, ALLEXCEPT ( ABC, ABC[Location], ABC[Brand] ) )
)
RETURN
SWITCH (
TRUE (),
NoOfRows = 2, IF (
RANKX (
CALCULATETABLE ( ABC, ALLEXCEPT ( ABC, ABC[Location], ABC[Brand] ) ),
ABC[Sales Revenue]
)
= 1,
"A",
"B"
),
NoOfRows = 3, IF (
RANKX (
CALCULATETABLE ( ABC, ALLEXCEPT ( ABC, ABC[Location], ABC[Brand] ) ),
ABC[Sales Revenue]
)
= 1,
"A",
"B",
“C”
),

ABC[Cumulated Percentage] <= 0.8, "A",
ABC[Cumulated Percentage] <= 0.95, "B",
"C"
)

@Mack1int,

Please change your DAX formula to the following:

ABC Product = 
VAR NoOfRows =
COUNTROWS (
CALCULATETABLE ( ABC, ALLEXCEPT ( ABC, ABC[Location], ABC[Brand] ) )
)
RETURN
SWITCH (
TRUE (),
NoOfRows = 2, IF (
RANKX (
CALCULATETABLE ( ABC, ALLEXCEPT ( ABC, ABC[Location], ABC[Brand] ) ),
ABC[Sales Revenue]
)
= 1,
"A",
"B"
),
NoOfRows = 3, IF (
RANKX (
CALCULATETABLE ( ABC, ALLEXCEPT ( ABC, ABC[Location], ABC[Brand] ) ),
ABC[Sales Revenue]
)
= 1,
"A",
IF (
RANKX (
CALCULATETABLE ( ABC, ALLEXCEPT ( ABC, ABC[Location], ABC[Brand] ) ),
ABC[Sales Revenue]
)
= 2,"B",
"C"
)),
ABC[Cum Percent] <= 0.8, "A",
ABC[Cum Percent] <= 0.95, "B",
"C"
)
