I have a very simple question but with Qlikview it seems not that simple. I have two columns the NPS column is aggregated and I have to calculate that on the montly basis. The problem I am facing in joining the data from two different tables. I have to make the line graph to show the development of both the question _name. for example I want to have
" if(question_name='nps' and ROUND(sum(if(NPS='Promotor',1)) / count(TOUCHPOINT)*100
