Hi Mishra, Thanks for the quick response.
I will eventually use a dimension to set the context. But considering this is not working, I have been trying all permutations and combinations. Here's another observation :
When I add an additional row to the same table and apply the SUM function, it works like a charm. However, if I take it out of the table into, let's say, a separate table or report, #Multivalue error crops up. Again attaching screenshot.
