SSRS 报告给我一个聚合错误

Question

尝试在 SSRS 中做一些数学运算并遇到此错误。

The Value expression for the text box ‘totalboxes3’ has an inner aggregate in an outer aggregate that specifies a dataset scope.  An aggregate that specifies a dataset scope cannot contain other aggregates.

我正在使用表达式：

=Sum(Fields!GP_Goal.Value, "Main") / Sum(Sum(Fields!Smartphone_Postpaid.Value) - Sum(Fields!CPE_Postpaid_Only.Value), "Main")

我是 SSRS 的新手，所以我想了解这是在问我什么以及如何解决它。

我也试过

=Sum(Fields!GP_Goal.Value, "Main") / Sum(Sum(Fields!Smartphone_Postpaid.Value, "Main") - Sum(Fields!CPE_Postpaid_Only.Value, "Main"))

Answer 1

问题是这样的：

Sum(Sum(Fields!Smartphone_Postpaid.Value) - Sum(Fields!CPE_Postpaid_Only.Value)

不需要外部SUM，只需减去总和并在总和内指定数据集：

=Sum(Fields!GP_Goal.Value, "Main") / (Sum(Fields!Smartphone_Postpaid.Value, "Main") - Sum(Fields!CPE_Postpaid_Only.Value, "Main"))
