Hi All,
I would like to count a sort of diversity per person and per month. Sample data: Customer Engineer Date A JP 01/11/2009 A Bill 01/11/2009 A Bill 01/11/2009 A JP 01/11/2009 B JP 01/11/2009 A JP 01/12/2009 B Bill 01/12/2009 C Bill 01/12/2009 D Bill 01/12/2009 E Bill 01/12/2009 In November, JP has served customers A & B, Bill only for A. The result for JP is 2 while for Bill, it is 1. In December: JP=1, Bill = 4. With {=COUNTDIFF((A2:A11)&(B2:B11))} I am already able to calculate over the whole range the differing combinations, but how to include the criteria person and month? Any help will be very appreciated. With kind regards, JP |

Which version of Excel has this COUNTDIFF function, or is it a 3rd part
add-in? -- David Biddulph "JP Ronse" wrote in message ... Hi All, I would like to count a sort of diversity per person and per month.

Hello JP,
If you do not want to use a Pivot Table select a sufficiently long range with two columns and array-enter =Pstat("count",TEXT(C1:C999,"YYYYMM")="200912",B1: B999,A1:A999) Pstat you can find he http://sulprobil.com/html/pstat.html Regards, Bernd |

Hi David,
You are right, it is included in MoreFunc for Excel (Morefunc is a freeware library of 67 new worksheet functions for Excel, created and developped by Laurent Longre). So, I better do not use this function if I want to share the workbook with the colleagues. Good remark. With kind regards, JP "David Biddulph" <groups [at] biddulph.org.uk wrote in message ...

Hi Bernd,
A pivot table is not an option in this project as the figures are for the management only, the employees are allowed to consult their own figures but not the ones of their colleagues. I know that you have written a lot of very useful functions but as most of the colleagues are Excel dummies, I prefer to work it out with the standard Excel functions, if possible.

You can embed the Morefunc add-in into the file if you're using a version of
Excel prior to Excel 2007. I'm not sure about doing it with Excel 2007. That way, if you distribute the file the recipients don't need to have the add-in installed on their machine. Morefunc is one of the better add-ins available so don't let Bernd try to convince you otherwise. I prefer to work it out with the standard Excel functions, if possible Try this array formula** ... Data in the range A2:C11 In the formula: Cust (customer) refers to Sheet1!$A$2:$A$11 Eng (engineer) refers to Sheet1!$B$2:$B$11 Dates refers to Sheet1!$C$2:$C$11 I'm assuming the dates are all within the same year so we're only going to test the dates for the month. E2:E3 are the 1st of the month dates 1/11/2009, 1/12/2009 F1:G1 = JP, Bill Enter this array formula in F2: =SUM(IF(FREQUENCY(IF(Eng=F$1,IF(MONTH(Dates)=MONTH ($E2),MATCH(Cust,Cust,0))),ROW(Cust)-MIN(ROW(Cust))+1),1)) ** array formulas need to be entered using the key combination of CTRL,SHIFT,ENTER (not just ENTER). Hold down both the CTRL key and the SHIFT key then hit ENTER. Copy across to G2 then down to F3:G3 Assumes there are no empty cells in the Customer range otherwise you could get errors. -- Biff Microsoft Excel MVP "JP Ronse" wrote in message ...

Hello,
... Morefunc is one of the better add-ins available so don't let Bernd try to convince you otherwise. Definitely. ... Point is: Morefunc can be as fine as anybody wishes for - without a license or without open source code you run the risk that it contains a virus or that you lose its functionality in future. That's why most companies' policies are not allowing to use it (or any of this kind). JP obviously intends to use his solution in his company. So let us not suggest to him to use Morefunc without checking his company's IT policy. Whether or not you agree to the number 1 of my Excel Don'ts http://sulprobil.com/html/excel_don_ts.html is a stronger but different point: What I cannot use in my company I won't use at all.

Hi Bernd,
You have a point with your remark on the company policy. Although not explicitly forbidden, our IT department will not support it. Therefore, I used the function that T. Valko suggested.

Hello JP,
... You have a point with your remark on the company policy. Although not explicitly forbidden, our IT department will not support it. Therefore, I used the function that T. Valko suggested. ... Ok, since you ticked the first point off, have a look now at the second one of my Excel Dont's, please: http://sulprobil.com/html/w-rule.html Avoid array formulas you (or the majority of your colleagues) do not understand or which you will fail to maintain later on. My thesis is that there are brilliant people around here suggesting nifty (array) formulas. But 95% (hmm, maybe even 99%) of all Excel users do not fully understand them, and the (array) formulas are not tackling the right problem space anyway. A huge bulk of the questions here can and maybe should be reasonably answered with Pivot tables (I suggest to search for Herbert Seidenberg's Pivot table solutions here). And another nice part of the challenges can be solved with VBA macros which encapsulate the functionality so that the casual user can easily use them (I suggest to have a look at my website). Before you "give in" to an array formula I suggest to think about helper columns and normal worksheet functions. Maybe you are satisfied with Biff's suggestion for now. But I suggest to put my suggestion into a cell comment next to his formula. I bet somebody will struggle with the array formula later on. Kind regards, Bernd |

Hello Biff,
... you run the risk that it contains a virus or that you lose its functionality in future. And you run that exact same risk using one of your UDFs. No. My UDFs are open source, fairly short, and a competent third person could easily adapt them to any future Excel version, I honestly believe. ... So, if you don't understand a "complex" array formula what are the chances that you're going to understand VBA code? You do not need to understand to program or to maintain them, you need to know how to use them - that's encapsulation. ... His solution to *everything* is a pt and he only posts solutions for Excel 2007. What about the people that don't use Excel 2007? I guess they're SOL. ... Not to *everything*. But have a look at http://sulprobil.com/html/pfreq.html (look at the "statistic on engineers" example, please). You can see that yours and Harlan's approach is about 6x faster than my Pstat approach for 100 data records. But for 1,000 data records my VBA approach is already about 5x faster than yours and Harlan's (who's falling over if there is any empty record, btw). And the approach which I deem to be state-of-the-art is another 3x faster: Prepare the data with Pfreq and then apply a Pivot table. You can see all variants in my sample file(s). Biff, I like your and Harlan's clever solutions and I think I learned a lot from both of you. But for many Excel challenges a Pivot table seems to be a preferrable solution. Btw: I think its not fair to say that I only post Excel 2007 solutions. I publish my worksheet formulas and my VBA macros which can be used in earlier versions as well. Regards, Bernd |

Hello Biff,
Fair enough. It's easy for me to watch out for COUNT(1/FREQUENCY()), SUM(... (FREQUENCY()) or SUMPROUCT(()/COUNTIF()) suggestions and to point out what Charles already stated some time ago. I cite him at: http://sulprobil.com/html/count_unique.html There are no useless posts. They can still serve as a bad example. Regards, Bernd |
