解决 Tableau 中 IF 结果的聚合和非聚合混合错误

Question

我正在尝试在 Tableau 中执行以下操作。

如果选择的关键指标是销售额或数量（非聚合字段），则调用计算 1，否则调用计算 2。

IF ATTR([Choose Key Figure])= "Sales"
THEN [Periodic Calculation]
ELSEIF ATTR([Choose Key Figure])= "Volume"
THEN [Periodic Calculation]
ELSEIF ATTR([Choose Key Figure])="profit"
THEN [Periodic Calculation 2]
ELSEIF ATTR([Choose Key Figure])="price per unit"
THEN [Periodic Calculation 2]
END

但是我收到以下错误： "Cannot mix aggregate and non-aggregate comparisons or results in 'IF' expressions."

定期计算

IF [Choose Vol/NNS]="NNS"
AND [Choose Period]=-1
AND DATEDIFF("month",[Dates], [Choose Current Month])<2
AND
DATEDIFF("month",[Dates],[Choose Current Month] )>0
then [(Actuals+Planned) NNS]
ELSEIF [Choose Vol/NNS]="Volume"
AND    [Choose Period]=-1
AND DATEDIFF("month",[Dates], [Choose Current Month])<2
AND
DATEDIFF("month",[Dates],[Choose Current Month] )>0
THEN [(Actuals + Planned) Volume]
ELSEIF [Choose Vol/NNS]="NNS"
AND [Choose Period]=-3
AND DATEDIFF("month",[Dates], [Choose Current Month])<4
AND
DATEDIFF("month",[Dates],[Choose Current Month] )>0
then [(Actuals+Planned) NNS]
ELSEIF [Choose Vol/NNS]="Volume"
AND [Choose Period]=-3
AND DATEDIFF("month",[Dates], [Choose Current Month])<4
AND
DATEDIFF("month",[Dates],[Choose Current Month] )>0
THEN [(Actuals + Planned) Volume]
ELSEIF [Choose Vol/NNS]="NNS"
AND [Choose Period]=-6
AND DATEDIFF("month",[Dates], [Choose Current Month])<7
AND
DATEDIFF("month",[Dates],[Choose Current Month] )>0

AND     [Choose Period]=6
AND DATEDIFF("month",[Dates], [Choose Current Month])<0
AND
DATEDIFF("month",[Dates],[Choose Current Month] )>-7
THEN [(Actuals + Planned) Volume]

任何人都可以帮助解决这个错误吗？

谢谢。

Answer 1

如果[选择关键值]是一个参数，[定期计算]和[定期计算2]是行级（非聚合）计算，那么您可以：

删除计算字段中对 ATTR() 的所有调用或
删除对 ATTR() 的所有调用，并在每次引用 [Periodic Calculation] 或 [Periodic Calculation 2] 时调用 SUM() 等聚合函数或
保持对 ATTR() 的调用并在每次引用 [Periodic Calculation] 或 [Periodic Calculation 2] 时调用 SUM() 等聚合函数

1和2的区别在于你的计算字段的聚合函数是在计算内部指定还是在使用它的Tableau工作簿架子上指定。

在这种情况下没有真正的理由选择第三种方法，因为参数一次只能有一个值，所以 ATTR() 调用没有用。
