DAX 从矩阵中的年份或季度中减去固定值

Question

需要从克莱斯勒矩阵视觉对象中的年份和季度汇总中减去设定值。多年的数据是按月计算的，需要对Chrysler only进行固定调整，每个季度为 5，每年为 15，没有总计低于零。

预期结果：

Date	Aston Martin	BMW	Chrysler	Grand Total
2020	0	27.36	26.22	53.58
Qtr1	0	0	7.99	7.99
Qtr2	0	17.34	9.15	26.49

Answer 1

假设：您有一个包含 YearQuarter 列的日期表（不一定标记为日期表）、一个包含每个组的键的 Groups 表，以及 Table 表中的 SumValue 等简单度量。

(Measure on Table table)
SumValue := SUM('Table'[Value])

(Measure on Table table)
CustomChrysler := 
VAR YearQuarterGroup = 
    CROSSJOIN( 
        VALUES( Dates[YearQuarter] ),VALUES( Groups[Group] ) 
        )
VAR Result = 
SUMX(
    YearQuarterGroup, 
    VAR SumVal = [SumValue]
    VAR Amount = IF( Groups[Group] = "Chrysler", SumVal - 5, SumVal )
    VAR AmountGreaterThanZero = IF( Amount < 0, 0, Amount )
    RETURN
    AmountGreaterThanZero
    )
RETURN Result

更新： 哪一个？

CustomChrysler2 := 
VAR YearQuarterGroup = 
    CROSSJOIN( 
        VALUES( Dates[YearQuarter] ),VALUES( Groups[Group] ) 
        )
VAR YearGroup = 
    CROSSJOIN( 
        VALUES( Dates[Year] ),VALUES( Groups[Group] ) 
        )
VAR ResulYearQuarter = 
SUMX(
    YearQuarterGroup, 
    VAR SumVal = [SumValue]
    VAR Amount = IF( Groups[Group] = "Chrysler", SumVal - 5, SumVal )
    VAR AmountGreaterthanZero = IF( Amount >= 0, Amount) //BLANK
    //VAR AmountGreaterThanZero = IF( Amount < 0, 0, Amount ) //Zero
    RETURN
    AmountGreaterThanZero
    )
VAR ResultYear = 
SUMX(
    YearGroup, 
    VAR SumVal = [SumValue]
    VAR Amount = IF( Groups[Group] = "Chrysler", SumVal - 15, SumVal )
    VAR AmountGreaterthanZero = IF( Amount >= 0, Amount) //BLANK
    //VAR AmountGreaterThanZero = IF( Amount < 0, 0, Amount ) //Zero
    RETURN
    AmountGreaterThanZero
    )
RETURN 
SWITCH(
    TRUE(),
    ISINSCOPE(Dates[Quarter]), ResulYearQuarter,
    ResultYear //ISINSCOPE(Dates[Year]) and Grand Total
    )
