Can't find any information about this function in help.
The function FieldElemNo() is present in environment QlikView, but it is not in Qlik Sence, and all the values it will result in -3. Maybe this is an out-of-date function, inferred from circulation?
I tried in on my data data (string and numeric with different lengths) and the result is still -3.
Qlik Sence Desktop does not have this function
In Qlik Sense desktop you can find and use it in expression editor in frontend.
In the picture above, it seems like there is no this function in the hint list. And in the code on it QS "swears"
Кароче я так понял, что это ненужная в сенсе функция, которую разрабы забыли убрать со времен вью.
Let's wait, maybe more experienced colleagues will tell us the truth
Probably this is it. It also does not exists in qlik.help.com.
