SSRS表达式导致错误

Question

I have the following expression in SSRS:-

=IIf(IsNothing(Fields!Hours.Value), 0, Sum(Fields!Hours.Value) / Sum(Fields!ReportingHours.Value))

The expression appears as #Error . I removed the division part of the equation, leaving just this:

=IIf(IsNothing(Fields!Hours.Value), 0, Sum(Fields!Hours.Value))

Then the correct numbers appear. If I perform an addition operation, the calculation also errors out. It seems that it does not like something about performing mathematical operations when using the Sum() function. If I do simple division without the Sum, as in this expression:

=IIf(IsNothing(Fields!Hours.Value), 0, Fields!Hours.Value / Fields!ReportingHours.Value)

Then numbers show up fine. It is only when I have the Sum() function on the expression that causes an error. Any ideas as to how to fix this?

Answer 1

Try the following expression:-

=IIf(IsNothing(sum(Fields!Hours.Value)), 0, Sum(Fields!Hours.Value) / Sum(Fields!ReportingHours.Value)

EDIT

I have edited my previous post.
