Would you please recommend methods by which I may improve performance that have to do with sorting? My problem is that I have many rows (for example, one customer/product is one row) and many dimensions (hundreds) and I need to display the top "x" of these products on a per row level basis so pre-aggregating and an additional table are not options due to the complexity. QlikView needs to sort the entire database in order to present the top x. Is there a way to limit on a per query basis (i.e. after the dimensions are indicated)? Any suggestions are much appreciated!
