使用RunningValue嘗試使用我的報告矩陣下面的表達式:在SSRS
=RunningValue(Fields!orderCount.Value,SUM,"RedemptionData")
但它給人的錯誤:
The Value expression for the text box '' has a scope parameter that is not valid for RunningValue, RowNumber or Previous. The scoke parameter must be set to a string constant that is equal to the name of a containing group within the Tablix''.
任何想法我可能是做錯了?
乾杯
