I am getting "The expression used for the calculated filed '=RunningValue(Fields!QTYTONS.Value,SUM,"rv1") includes an aggregate, RowNumber, Running Value, Previous or lookup function. Aggregate, RowNumber, RunningValue, Previous and lookup functions cannot be used in calculated field expressions.
I tried many variations, =RunningValue(Fields!QTYTONS.Value,SUM, Nothing) -=RunningValue(Fields!QTYTONS.Value,SUM,"DataSet1") - to no avail.
All I want is to have a running total of the tons that were received and shipped. I tried Aggregate functions and SUM functions and all of what I tried get the same message.
I have a row group called "rv1" and a DateSet called "DataSet1".
