yesterday a top 10 member explain me how to create a conditional SUM using set analysis expresion. But today another problem comes to my mind when I wrote this code in text object properties - general tab:
In first case, data result is ok but I´m only choosing one account data. It was first step I want to write to validate my sentence, but when I expand it with LEFT function to take a range I really want, something is wrong and it doesn´t work.
There are very good sample codes in this forum and in the "Share QlikViews" section where you can finde some other people's code and solutions to problems that may be very similar to yours. Just a query on Google for
set analysis site:qlik.com
will return a lot of posts, wikis and qvw files with those examples.
