Dynamic Modifier in Set Analysis

Hello, 

So what I have here is 1 table:

ItemTypecalendar.idquantity
1Sale400010
1Sale400010
1Purchase400112
1Purchase400112
2Sale400214
2Sale400214
2Purchase400316
2Purchase400316

 

What I am trying to do is make a table with: 1) Item 2) Sale date  3) Order quantity

So "Sale date" is minimum date when sale took place (4000 for item 1 and 4002 for item 2) formula: date(MIN({<Type={'Sale'}>}calendar.id))

But I struggle to come up with Order quantity formula, I want to Sum quantity sold on that minimum date on each item.

What I came u with:

SUM({<calendar.id={'$(=MIN(calendar.id))'}, Type={'Sale'}>}quantity)

But  calendar.id={'$(=MIN(calendar.id))'} ends up 4000 for both rows so it is correct for first line, but wrong for second one

I know I can do it by adding one more field in load script, but making it like this is what I need, thanks

P.S. Atached sample

tbl1:
LOAD

'Y' as Flag
Resident tbl
group by Item;

exit SCRIPT;

and then add straight table with below expression

=SUM({<Flag={'Y'}>}quantity)

hank you for your reply. That would work, but I need formula in chart, without any modification in script.

Hi Luksse7,

if you can't change your script, this could be your solution in your front end:

MinDate.jpg

Your expression is related to the calculated dimension

If(calendar.id = Date(Aggr(Min(calendar.id), Item)), Sum(quantity))

this will give you the expected result (see the picture).

By the way, you can hide 'calendar.id' under the Presentation tab.

Hope this helps
