Hi everyone!

Does someone know if it is possible to use a set expression an a set expression?

I want to show Sales starting from 01.10.2017 until the last day of previous month.

So far, I used this expression.

Every month, I have to update the "Last day of the previous month" in many tables and charts. So now I thought I could create a variable with "the last day of the month", where I just have to update the date once in the variable.

I tried:

vLastDayofPreviousMonth = 43737 (which is 30.09.2018)

Sum({$<date= {'<43008 < $(vLastDayofPreviousMonth) } > } Sales)

but it didnt work. Maybe someone has a hint for me to solve this problem?

Thank you very much

May be try this

Sum({$<date = {"$(='>' & 43008 & '<' & Num(MonthStart(Today()) - 1))"}>} Sales)

Hi,

you can try something like this (100% dynamic):

=sum({<date={">$(=AddYears(MonthStart(Today()),-1))<$(=MonthEnd(Today(),-1))"}>}Sales)

PS: verify the format of your date field, it should be exactly the same than the output of the functions inside the variables

Hi youssef,

thank you very much, this solved my problem perfectly!

I don't know yet: When do I use double comma (") and when single comma (')?

Is there any suggestion to learn Set Expression beside the QlikView-manual?

Thank you again!

Hi Jacob

I had a similar requirement recently

But the user wanted to select one  MonthYear and have a Month total shown and also a YTD figure shown from 1/10/17 to say 30/9/18 (when selecting MonthYear Sept 2018.) But to show 1/10/18 to 31/10/18 when selecting Oct 2018. Or 1/10/16 to 31/8/17 when selecting Aug 17 etc.

I did this using MonthAgo. Its another way of achieving the same thing without having to change the variable each month

Relative Calendar Fields

-SUM({<

YearFin = { "=$(=(YearFin))"}

,MonthsAgo = { ">=$(=min(MonthsAgo))  "}, MonthYear  =

>}ActualValue)

-SUM({<

,MonthsAgoYTD = { ">=$(=MonthsAgoYTD)"}   , MonthYear  

,fYear = {"$(=(fYear)-1)"}

>}ActualValue)
