Most frequent table value for a dimension

[#1]

Hi all,

I have a table like:

Customer | Item | item category | price | qty

I would like to get as result something like

Cutomer (as a dimension) | Turnover (as qty * price) | most frequent ordered category

The result is provided through a table drawn as a chart.

and I don't have any idea on how to turn the expression to get that "most frequent ordered category"

Any idea?

Thanks in advance for your usual support

I think i found the answer mode()

[#3]

The mode() fonction seems not to work properly, in a specific case I have an item_category that is equal to null and the customer order more than 10 items (on a total of 15) from a category "A" and QV returns "null" as the result of mode()

Try something like this:

if(item_category <> NULL(), mode(item_category))

[sivarajs]

do something like aggr(max(category),customer)

Thank you both but unfortunatly it does not work.

I extracted 3 cases where I have a wrong answer with the mode() function:

Customer	Order Id	Item	Item Categrory	Price

CUST C	89380	Product 43	-	23,99
CUST C	89380	Product 44	CAT B	34,89
CUST C	89380	Product 45	CAT A	62,81
CUST C	89380	Product 46	CAT B	17,52
CUST C	89380	Product 47	CAT A	10,89

For Cust B i can understand as frequence for CAT B and CAT C is equal to 9

But for Cust C, I would have Cat B (freq=13 vs 4 or 1) and for Cust A the result should be Cat B (freq 4 vs 1,1,3,2)

Can your post your .qvw and some data so that we can see it?

[ToniKautto]

If more than one value is equally commonly occurring NULL is returned.
