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?

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

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

Bernd

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.

With kind regards,

JP

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.

Hi,

Your function calculates exactly what I need. Many thanks for your
assistance and your time.

If there would be multiple result formulas, it may be better to define
a 4th name BIN referring to the formula =ROW(Cust)-MIN(ROW(Cust))
(omission of +1 intentional). The you could use formulas like

=COUNT(1/FREQUENCY(MATCH(Cust,Cust,0)*(Eng=F$1)*(MONTH(Date s)=MONTH
($E2)),Bin))-1

which doesn't have to be entered as an array formula [because it
doesn't call IF, and FREQUENCY always returns an array, so its results
are handled like array constants].

Hello,

...

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.

Bernd

Hi Harlan,

Is also a nice alternative. Sorry for late reply.

You could present a filtered pivot table to the employees, showing only their
own information. And also present an unfiltered table to management.
