You've probably noticed as you work on this problem, that you are not 
having quite as much fun as you usually do. You will succeed only if you 
are determined, unreasonably stubborn and masochistic. I generally read the 
code and attempt to duplicate it, step by step with ISQL until I can match 
the totals. Having done this, I can understand and explain what is 
happening, even if it is not correct. If possible, isolate and work with a 
small subset of the data that you know is a problem. Be aware that logic 
errors in the report program could be including or excluding data 
incorrectly. Try to sleep a little every 36 to 48 hours, and bathe 
occasionally or your co-workers will complain.

Good luck
