I am trying to combine 2 tables from different databases into 1 report. (Can't do a join). SO right now I have the data in 2 separate datasets. There isn't a key that relates the two datasets, only 'Date' fields. IE: I am joining the data that occurs within each month between the 2 datasets. I have not had any luck grouping this data together, as I am always getting the error "Report item expression can only occur within the current data set scope..." BOL doesn't seem to cover this area, so I'm looking for any help/documentation on this, or if this is even possible. Thanks.
