Reporting services 获取一个Nan错误SSRS

得到一个错误。我的原始声明是：

=SUM(Fields!Outstanding_Commitments.Value/Fields!Conversion.Value, "Cost") 

收到NaN错误后，我将代码更改为以下内容：

=IIF(Double.IsNAN(SUM(Fields!Outstanding_Commitments.Value/Fields!Conversion.Value, "Cost"))
,0,
SUM(Fields!Outstanding_Commitments.Value/Fields!Conversion.Value, "Cost"))

使用第二部分根本不能为我提供任何值。有点不对劲

提前感谢

试试下面的表达方式

=SUM(
Iif(Fields!Conversion.Value=0,0,Fields!Outstanding_Commitments.Value)
/
Iif(Fields!Conversion.Value=0,1,Fields!Conversion.Value)
, "Cost")
