I am having trouble doing a running total of the following data item called [Total]
[Total] has expression
total( [measure] within set set([row_item])) +[Journal]
An ideas??
I've never had luck using running functions with olap.
Try this instead:
total([Sales]
within set periodsToDate (
[Cube].[Dates].[Years].[All],
currentMember ([Cube].[Dates].[Years])
))
