I have a question. I am trying to write some dynamic code in an expression in Qlik Sense. Essentially, I am trying to dynamically construct the name of a field queried after. So, let's assume there is a field in my code called 'XYZ123', and I am trying to achieve the SUM(XYZ123), but in such a way that 'XYZ' and '123' are both stored as variables and are only concatenated within the query.
I am managing to achieve the desired string by using:
but it doesn't work whenever I try to pass it into an expression. I tried to do it more or less like that:
but I only managed to get 0 back. Do you know if there is any way of doing this efficiently in the front end?
