Reporting services SSRS报告生成器差异%

我试图计算差异百分比，并避免被0除的错误

以下代码适用于总体差异百分比

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

我现在试图将其限制在某个类别，并尝试使用下面的表达式

    =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)

=
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))
)

---

它似乎没有查看类别值，因为它继续给我提供总体差异。如果有任何帮助，我将不胜感激，因为我不知道从这里到哪里去

您是否尝试将附加条件移动到其他两个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)

---

必须在表达式的每个和中使用Iif

    =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)

=
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))
)

另一种方法是使用如下自定义代码

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，比如：

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

---

最初尝试时收到错误，我将其更改为，

=IIf（Sum（Fields！Baseline.Value）=0和Fields！Category.Value=“Resources Capital”，0，Sum（Fields！test.Value））/IIf（Sum（Fields！Baseline.Value）=0和Fields！Category.Value=“Resources Capital”，1，Sum（Fields！Baseline.Value））

它仍然没有正确计算我的错误，总和应该在iif语句之外：总和（iif（Fields！Baseline.value=0和Fields！Category.value=“Resources Capital”，0，Fields！test.value））/sum（iif（Fields！Baseline.value=0和Fields！Category.value=“Resources Capital”，1，Fields！Baseline.value））它给了我一个错误。这看起来应该相当简单，但我可能不得不重新考虑它。我使用了

=sum（iif（Fields！Baseline.value=CDec（0）和Fields！Category.value=“Resources Capital”，CDec（0），Fields！test.value））/sum（iif（Fields！Baseline.value=CDec（0）和Fields！Category.value=“Resources Capital”，CDec（1），Fields！Baseline.value））

我没有收到错误，但我应该得到-188%，但得到了13%。
