I'm new to IA. I did a column analysis returned 3.7 million records and it stays in Analysis Database if I need to keep this results. However, I need to do more column analysis, the analysis DB will run out table space quickly. I'd like to know if I should use Sample data instead of full table data, but how much data that I should use for a formal (not for test) run? I know this will depend on Business, but does IA have a way to work out the tabe space problem in column analsis? Please help.
