Powerbi Dax从rankx测量中获得单秩结果

如何从rankx测量中获得单个结果，例如，我需要“Test3”的结果，在本例中为3

DAX formula for rank: =
RANKX(
   ALLSELECTED(CompetitionComp);
   CALCULATE(
       SUM(CompetitionComp[Base price WS])
   )
)

结果:

Name    Ranking
test1  | 1
test2  | 2
test3  | 3
test4  | 4
...

我不确定这是否是你想要的：

DAX formula for rank 3: =
VAR _rank_3 = RANKX(
   ALLSELECTED(CompetitionComp);
   CALCULATE(
       SUM(CompetitionComp[Base price WS])
   )
)

RETURN IF(_rank_3 = 3, SUM(CompetitionComp[Base price WS]) )
