我試圖在SSRS計算字段執行聚集和正在以下錯誤:SSRS Aggreation上計算字段
[rsAggregateReportItemInBody] The Value expression for the textrun 'Textbox43.Paragraphs[0].TextRuns[0]' uses an aggregate function on a report item. Aggregate functions can be used only on report items contained in page headers and footers
這是我試圖用公式:
=Sum(ReportItems!PlanPurchPrice.Value, "Select_UCPUtilization")
在這種情況下PlanPurcPrice也是一個表達:
=First(Fields!PawPlanPurchPrice.Value, "Select_UCPUtilization")
對此有何建議將不勝APPR eciated。
