RANKX avoid duplicate

DAX DAX Calculations
1

Hi all,

I’ve some issue with my RANKX, currently having same ranking. I’ve watched and tried this sample :
Developing Custom Tiebreakers in RANKX - DAX Tutorial - YouTube

However still it is showing same rank, even there is some skip rank. Strange is in the table it looks no duplicate, but the result is like I just said.

By looking at the image, column Turnover days tiebreaker actually already don;t have any duplication, but result is some duplicates and some skipped.

So here are the DAX:

  1. Ranking my value (Turnoverdays)

Rank product tiebreaker =
VAR tmp = [Turnover days]
VAR tmpRank = IF(
tmp <> 0,
RANKX(
FILTER(
ALL(‘Released products’[Product number]),
[Turnover days] <> 0),
[Turnover days] ,DESC,Dense
),
BLANK()
)

VAR RankScale = DIVIDE(tmpRank + RAND(),100)

RETURN IF(
tmp <> 0,
RankScale,
BLANK()
)

  1. Adding my value (Turnover days) into the result of point 1. And this already strange because it looks the add is wrong.

Turnover days tiebreaker = [Turnover days] + [Rank product tiebreaker]

  1. Ranking based on no 2. While no 2 result has no duplicate, I’ve created this :

Rankx Contest Final =
VAR temp = [Turnover days tiebreaker]
RETURN IF(
temp <> 0,
RANKX(
FILTER(
ALL(‘Released products’[Product number]),
[Turnover days tiebreaker] <> 0),
[Turnover days tiebreaker],
DESC,
Dense
),
BLANK()
)

On the list, we can see “Turnover days tiebreaker” already all unique, but result from point 3 (Rankx contest final) is still wrong.

Thanks,

@Toni Don’t use RAND for breaking ties. PERIOD.

Refer to this:

Ranking (Breaking Ties) for a Category based on a Measure with duplicate values for categories - DAX Calculations - Enterprise DNA Forum
