If i have a field that is just a summary field like this
=Sum(Fields!Quantity.Value, "bActAll")
and another from a different dataset in the same report like this =Sum(Fields!Quantity.Value, "bActAll")
How can I add a calculated field that subtract (or percentage) one from the others?
I see that calculated field can be added under a dataset, but how can they work across datasets in the same report?
Appreciate any help!
