## Question w Distinct Count Aggregations

Im not observing the expected result of an aggregation of a distinct count. See the below screenshot;

I am expecting a value of 4.

The expression is the following;

=

if(

(
sum(if(vYear-1=Year and vYear_Week=Year_Week,Sales_Units,0))+

sum(if(vYear-1=Year and vmaxVYrWk=Year_Week,Ending_Inventory_Units,0))>0)

,
count(DISTINCT(Location_Id))

)

Using a Total Mode = Sum will return a value of 4; however there are several other product/ calender dimensions in this chart-- and a "sum" does not appear to work when exposing them.

Also, the chart can be changed to a pivot table on-demand; so this aggregation must also support an approach that does not include a different "total mode".

Thanks.

## Re: Question w Distinct Count Aggregations

i belive i may have solved.. basic problem with expression;

=

if(

(
sum(if(vYear-1=Year and vYear_Week=Year_Week,Sales_Units,0))+

sum(if(vYear-1=Year and vmaxVYrWk=Year_Week,Ending_Inventory_Units,0))>0)

And

,
count(DISTINCT(if(vYear-1=Year and vYear_Week=Year_Week,Location_Id)))

)

## Re: Question w Distinct Count Aggregations

You are getting the Expression Total and I think it's calculated right be QV.

To only count the location ids where condition is fulfilled, you can try something like:

count(

{<Location_Id = {"=sum( {<Year = {\$(=vYear-1)}, Year_Week= {\$(vYear_Week)} >} Sales_Units)+sum({<Year = {\$(=vYear-1)}, Year_Week = {\$(vmaxVYrWk)} >} Ending_Inventory_Units) > 0"} >}

DISTINCT Location_Id)

## Re: Question w Distinct Count Aggregations

Hi

i used your code but something strange is occurring. so the following is what i am using as my expression- i added another condition as i do not want to count DC/ warehouse locations;

count

({<
Location_Id =
{
"=sum( {<Year = {\$(=vYear)}, Year_Week= {\$(=vYear_Week)} >} Sales_Units)
+sum({<Year = {\$(=vYear)}, Year_Week = {\$(=vmaxVYrWk)} >} Jeeves_Ending_Inventory_Units) > 0 And Location_Type <> 'DC'"
}
>}
DISTINCT Location_Id)

so i only want to count locations that have sales or ending inventory and are not a DC-- for that time period specified (last week)

so when i have selected a product it calculates perfectly as shown below

however when i dont have a product selected it doesnt seem to calculate as expected as shown below;

any ideas?

thanks!
