How many 'unique' customers has everyone been involved with?
This feels like it should be quite simple, but I'm really struggling...
I have a list of quotes all made by my salespeople, each one submits quotes for selling items to customers, sometimes the same customer will ask for quotes on 10 or 15 different items. for example, Fred has quoted a price (to Builders Inc) for bricks, another price for tiles, and another price for concrete, all for the same customer. These three items show up as three separate lines in my list, but each one of these three lines has the same customer name on it Fred has also quoted for other people and other sales people might have also quoted for stuff for 'Builders Inc' too So here's waht I'm after... I want a table of all my sales people, and next to each sales persons name, I just want the number of DIFFERENT customers they've quoted to, so for Fred, 'Builders Inc' must only show as one (even though it appears three times). I want a total number of unique customes that each sales person has had dealings with. I hope that makes sense Thank you M |

Try this array formula** :
A1:A20 = sales person B1:B20 = customer D1 = sales person Array entered** in E1: =SUM(IF(FREQUENCY(IF(A$1:A$20=D1,MATCH(B$1:B$20,B$ 1:B$20,0)),ROW(B$1:B$20)-ROW(B$1)+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. Assumes no empty cells in the customer range. -- Biff Microsoft Excel MVP "Michelle" wrote in message ...

Hi
If you have the data in say 3 columns Column A - Sales Rep Column B - Company Quoted Column C - Details of what they quoted You could easily summarise in a pivot table and get even more comprehensive set of analysis also. In the Pivot you can count Company quoted by Sales Rep Thanks Matt Michelle wrote: This feels like it should be quite simple, but I'm really struggling...

That's great - thanks. How can I find out how it works, so that I can do
similar things without asking for help in future? M "T. Valko" wrote in message ...

Hello,
Or array-enter into a sufficiently long area with 2 columns: =Pfreq(Pfreq(A1:A20,B1:B20)) Pfreq you can get he http://sulprobil.com/html/pfreq.html Regards, Bernd |

I don't know of a resource that I can direct you to where this type of
formula is explained. I can explain it in great detail but right now I don't have the time (I'm the worlds slowest typist). I'll post an explanation later tonight. -- Biff Microsoft Excel MVP "Michelle" wrote in message ... That's great - thanks.

How many 'unique' customers has everyone been involved with?
We want to count the unique customers for salesperson Joe. Let's use this
smaller data sample to see how this works: ........A............B...............D 1...Joe.....CustomerA......Joe 2...Sue....CustomerB 3...Tom....CustomerC 4...Joe.....CustomerA 5...Joe.....CustomerB =SUM(IF(FREQUENCY(IF(A$1:A$5=D1,MATCH(B$1:B$5,B$1: B$5,0)),ROW(B$1:B$5)-ROW(B$1)+1),1)) Result = 2 Everything is dependent upon the salesperson being Joe. So we use the IF function: IF(A$1:A$5=D1 (salesperson = Joe), to test the range A1:A5 for Joe. With this test we get an array of TRUE or FALSE. A1 = D1 = T A2 = D1 = F A3 = D1 = F A4 = D1 = T A5 = D1 = T Where this condition is TRUE we use MATCH to generate an array of values that we will then use to get the count of the frequencies from. MATCH returns the relative position of the lookup value within the lookup array. MATCH will find only the first instance of the lookup value when there are duplicate lookup values. The lookup values are the customer names and the lookup array is also the customer names. MATCH(CustomerA,B1:B5,0) = 1 MATCH(CustomerB,B1:B5,0) = 2 MATCH(CustomerC,B1:B5,0) = 3 MATCH(CustomerA,B1:B5,0) = 1 MATCH(CustomerB,B1:B5,0) = 2 Notice how there are 2 instances of 1 and 2 instances of 2. This is because of the duplicate lookup values CustomerA and CustomerB and that MATCH will only find the first instance of a lookup value.Where the IF function test is TRUE: IF(A$1:A$5=D1, the result of the IF function will be the corresponding result of the MATCH function. Where the IF function test is FALSE the result will also be FALSE: T..1 = 1 F..2 = F F..3 = F T..1 = 1 T..2 = 2 This array is passed to the FREQUENCY function and is the data array argument of the FREQUENCY function. The FREQUENCY function does a series of "count if's". It counts how many items in the data array meet certain conditions. In this case, those conditions are a series of numbers called the bins array. Since MATCH returns a series of specific numbers we want to count just how many of each of those specific numbers there are. Since the range we want to count is B1:B5 (5 rows), that means the result of MATCH could be a number from 1 to 5. So, we want to count how many 1s, 2s, 3s, 4s and 5s are in the data array. So, we need to tell the FREQUENCY function we want to count the numbers 1,2,3,4,5. We do this using this expression: ROW(B$1:B$5)-ROW(B$1)+1 That expression will return the array 1;2;3;4;5 ROW(B1)-ROW(B1)+1 = 1 ROW(B2)-ROW(B1)+1 = 2 ROW(B3)-ROW(B1)+1 = 3 ROW(B4)-ROW(B1)+1 = 4 ROW(B5)-ROW(B1)+1 = 5 At this point this is what the FREQUENCY function looks like: FREQUENCY{1;F;F;1;2},{1,2,3,4,5} As I mentioned above, FREQUENCY returns a series of "count if's" on the data array based on the values of the bins array. These are those "count if's" : count if data array is <=1 count if data array is 1 and <=2 count if data array is 2 and <=3 count if data array is 3 and <=4 count if data array is 4 and <=5 count if data array is 5 And these are the results of those "count if"s": {1;F;F;1;2} <=1 = 2 {1;F;F;1;2} 1 and <=2 = 1 {1;F;F;1;2} 2 and <=3 = 0 {1;F;F;1;2} 3 and <=4 = 0 {1;F;F;1;2} 4 and <=5 = 0 {1;F;F;1;2} 5 = 0 The logical FALSE is ignored. Now we're getting pretty close to the end result! The results of the FREQUENCY function are then passed to the outer IF function. At this point the formula looks like this: =SUM(IF({2;1;0;0;0;0},1)) We take advantage of a little known "trick" about the IF function. Typically, an IF function is made up of 3 arguments: logical test value if TRUE value if FALSE The logical test is usually a test for some condition. For example, the inner IF is using the logical test of: A$1:A$5=D1. It's testing each cell in the range A1:A5 to see if it equals what's in cell D1. The result of this test is either an array of TRUE or FALSE. If the result is TRUE then the IF function returns the value if TRUE argument. If the result is FALSE then the IF function returns the value if FALSE argument. In Excel, numbers can also be used to represent TRUE and FALSE. Typically, 1 = TRUE and 0 = FALSE. However, in Excel *any number other than 0* will be evaluated as TRUE. So, with our formula now looking like this: =SUM(IF({2;1;0;0;0;0},1)) We get this: IF 2 = T IF 1 = T IF 0 = F IF 0 = F IF 0 = F IF 0 = F Where the logical test is TRUE, return the value if TRUE argument of 1. Where the logical test is FALSE, return the value if FALSE argument of _____. Ah, now what? We haven't defined a value if FALSE argument. Since we haven't done that the IF function will return the default value if FALSE argument of FALSE. IF 2 = T = 1 IF 1 = T = 1 IF 0 = F = F IF 0 = F = F IF 0 = F = F IF 0 = F = F These results are then passed to the SUM function and summed to get our FINAL result: =SUM({1;1;F;F;F;F}) =2 So: Count the unique customers for salesperson Joe. =SUM(IF(FREQUENCY(IF(A$1:A$5=D1,MATCH(B$1:B$5,B$1: B$5,0)),ROW(B$1:B$5)-ROW(B$1)+1),1)) =2 exp101 -- Biff Microsoft Excel MVP "T.
