Yes thats correct, I am hoping that I will find software/addon that would think for me. However in programmed way. Even further - software/addon should have feature that works like ''human brains'' - particular filter's parameters shall be missing in the collection of BW addon. Example: for time perion (syntax: mm.yyyy) there might be only 02.2013, 03.2013, 05.2013 but if I define period from first month in 2013 to first month in 2014 the software/addon I am asking for should automatically ''know'' to include the other parameters such as 01.2013 (not yet added), 04.2013, 06.2013 and so on until, including (but for the values still available after refreshing file to most up to date version from people doing the upgrades of values), 01.2014. This is what I meant with ''human brains''.

It would save me/us a LOT of work so please don't just say nothing like this exist. There have to be some comparison tool that could work with BW customized isolated addon (but still located inside excel). Would save also months of time.

Give report out. Which report? Whatever I define as being interested for. But remember: I define what report I want and not what to compare.

I apologize but i don't understand neither of those two questions. Please clarify, perhaps on some example.

Most of your remaining, latest, reply is correct.

Since this conversation have been going on for a while, since I still don't have the name of the program and since Im aware the urgency is increasing mainly due to the fact when software will be working on particular file, the entire computer will be most likely frozen for whole week at least due to tens of millions of comparisons and all RAM used, I will mention another example (although i plan in completely different environment - manufactory) where could be the tool used:

Location: Hospital

Situation: Patients - increased number of patients in particular time period due to signs of similar diseases

Filters based on: parameters received in laboratories (blood, urine, etc), where had they been before sign of disease occured, what kind of signs occured, what they were doing, how soon they came to the doctor, location (air, potential dangerous gas, etc) analysis, any different disease particular patients had had before, any remedies they are regularly taking and many many many more - just about anything doctor (or staff in laboratories) would want to know and/or analyze

What I would define in the software: whatever im interested for, e.g. Patients in both gender and any age/nationality, who visited in the hospital in particular time period particular laboratories and went from those laboratores to particular departments/doctors. Obviously I wouldn't define which element of diagnosis would be compared with, e.g. people coming from particular city. This would be expected from the software. If software showed large irregularities per city, I would further dive into the software, run analysis again and this time perhaps set to define I am being interested in elements of air in that city in particular time period - perhaps there were some additions in the air that could risk human's health. Perhaps I would run analysis (I know it sounds crazy but I am further explaining only how I expect the software to work) of police records according to missing people or wanted people due to crime activities - perhaps someone used to randomly set dangerous substances when he/she received status of ''wanted person'' - if report pointed to someone, thats already some result I could pass forward to investigators, etc.

There are billions of possibilities I could define what I am interested for and the software I am looking for would provide the answer based on comparison between values. But of course values (unless logical ones such as mm.yyyy if defining time period) must be given, e.g. full list of people with status "wanted person" must be gathered and located inside parameters otherwise software cannot analyze.

What I would actually expect from the software: Report/answer with graph(s) WHY the disease occured.
