SSRS 报告给我一个汇总错误

【问题标题】：SSRS Reports giving me an aggregate errorSSRS 报告给我一个汇总错误

【问题描述】：

尝试在 SSRS 中做一些数学运算并得到此错误。

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")

我对 SSRS 很陌生，所以我试图了解这是在问我什么以及如何解决它。

我也试过了

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

【解决方案1】：

问题是这样的：

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

不需要外层 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"))
