Well, I can show you these 2 pictures
Report shows how the report should look like, I have three tables, Burin, Grom, Baracuda, each has its own dataset, which are named on the left side. The column Test should have an expression where it would calculate the difference between columns Grom and Burin (example)
Report2 show the query, as you can see its the same query for each document in a single datasource. But I have 3 different datasources, the result of which are 3 datasets on the left.
I have the same query on al three datasets. I get the same colums, just different COUNT(DocLinkDocID) value, and I need to show that difference. I hope I am making sense now :D
Sorry for the late reply, had a long weekend over here :)
