Power BI 可以测量静态值和动态值

Question

我有以下数据

IF OBJECT_ID('tempdb..#TBL') IS NOT NULL DROP TABLE #TBL
create table #TBL (category varchar(6), Year_Vs_Year VARCHAR(20),   Cost INT)
INSERT INTO #TBL VALUES
(null,'24/25 vs 19/20',7),(null,'24/25 vs 20/21',208),(null,'24/25 vs 21/22',98),

select * from #TBL

目前数据是这样的

在 power bi 中我写了下面的代码

Cost without current year = 
var a = MAX(Pathology[fiscal_year])
var b =CALCULATE(([Cost]),a= Pathology[fiscal_year])
var c = CALCULATE(SUM(Pathology[Cost]),ALL('Pathology'))
RETURN
c

给出了有趣的结果

预期产出应该是最大年份的值

所有值应为上面显示的最大年份值 谢谢

此 Dax 测量产生了预期结果：

Max Cost without Year = 
VAR __maxYear = CALCULATE( MAX( Pathology[fiscal_year]), ALL(Pathology ) )
VAR __result = CALCULATE( MAX( Pathology[Cost] ), Pathology[fiscal_year] = __maxYear )
VAR __subtable = 
    FILTER( 
        ALL( Pathology ), 
    Pathology[fiscal_year] = __maxYear 
)
VAR __sum = 
    SUMMARIZE( 
    __subtable, 
    Pathology[Category],  
        "@MaxCost", SUM( Pathology[Cost] ) 
    )

RETURN 
    IF( 
       HASONEVALUE( Pathology[Category]), 
       __result, 
       SUMX( __sum, [@MaxCost] ) 
    )
