SSRS表达式 - 求和两个字段

Question

我需要总结两个领域，但我不能。

你能帮助我吗？

=iif(Fields!ABC.Value= "", Nothing, Sum(Fields!PA.Value)) 
=iif(Fields!XYZ.Value= "", Nothing, Sum(Fields!PA.Value))

它不起作用：

=iif(Fields!ABC.Value= "", Nothing, Sum(Fields!PA.Value)) +
       iif(Fields!XYZ.Value= "", Nothing, Sum(Fields!PA.Value)) 

Answer 1

总结一下，我认为你只想默认为0而不是Nothing

=iif(Fields!ABC.Value= "", 0, Sum(Fields!PA.Value)) +
   iif(Fields!XYZ.Value= "", 0, Sum(Fields!PA.Value)) 

Answer 2

我认为他正在寻找的东西是这样的：

=Sum(IIF(Fields!ABC.Value = "", Nothing, Fields!PA.Value)
=Sum(IIF(Fields!XYZ.Value = "", Nothing, Fields!PA.Value)
