Question

我正在尝试计算方差百分比并避免除以0错误

以下代码适用于整体差异百分比

=IIf(Sum(Fields!Baseline.Value) = 0, 0, Sum(Fields!test.Value))  / IIf(Sum(Fields!Baseline.Value) = 0, 1, Sum(Fields!Baseline.Value))

我现在正尝试将其限制为某个类别并尝试使用以下表达式

    =IIF(Fields!Category.Value = "Resources Capital ",
IIf(Sum(Fields!Baseline.Value) = 0, 0, Sum(Fields!test.Value))
  / IIf(Sum(Fields!Baseline.Value) = 0, 1, Sum(Fields!Baseline.Value)), 0)

它似乎没有查看类别值，因为它继续给我整体差异。任何帮助将不胜感激，因为我不知道从这里去哪里。

Answer 1

您是否尝试将附加条件移至其他两个IIF表达式而不是添加另一个：

=IIf(Sum(Fields!Baseline.Value) = 0 and Fields!Category.Value = "Resources Capital ", 0, Sum(Fields!test.Value))
  / IIf(Sum(Fields!Baseline.Value) and Fields!Category.Value = "Resources Capital " = 0, 1, Sum(Fields!Baseline.Value)), 0)

Answer 2

你必须在表达式的每个SUM中使用Iif

=
IIf(
Sum(IIF(Fields!Category.Value = "Resources Capital",Fields!Baseline.Value,0)) = 0, 
0, 
Sum(IIF(Fields!Category.Value = "Resources Capital",Fields!test.Value,0))
)
/ 
IIf(
Sum(IIF(Fields!Category.Value = "Resources Capital",Fields!Baseline.Value,0)) = 0, 
1, 
Sum( IIF(Fields!Category.Value = "Resources Capital",Fields!Baseline.Value,0))
)

替代方案可能是使用下面的自定义代码

Public Function Divider (ByVal Dividend As Double, ByVal Divisor As Double)
If IsNothing(Divisor) Or Divisor = 0
  Return Nothing
Else
  Return Dividend/Divisor
End If
End Function

然后你可以写下你的表达式：

=Code.Divider(
Sum(IIF(Fields!Category.Value = "Resources Capital",Fields!test.Value,0)),
Sum(IIF(Fields!Category.Value = "Resources Capital",Fields!Baseline.Value,0))
)
