Hello,
I have a module that is getting the data via a TIMESUM formula. It's causing an issue since it was not summed up by the dimension. So I'm changing the formula and trying to include a SUM string but it's returning an error: An expression or constant may not be used as argument 1 of the function TIMESUM.
TIMESUM(SourceModule.Amount[SUM: SourceModule.Dimension], Time Assumptions.Start, Time Assumptions.End)
