Concatenating 3 tables in Data manager (in Qlik Sense)
I have to load 3 sheets (with same no. of columns) from same Excel files to Qlik Sense and then I want to unpivot these 3 tables (still maintain same no. of columns after unpivoting) and concatenate them into 1 big table. I can concatenate any 2 of them but when i try to concatenate the 3rd one, an error message will pop up! Anyone knows what is the possible root cause of it?
