I would appreciate some help, since I an newbie to QlikView with a very limited amount of time to learn.
I have a listbox with the following values (year and month concatenated):
202106
202103
202012
202009
202006
202003
201912
...
The user is allowed to select only one value from the listbox (e.g.202106) and the other value (202006 - a year ago with regard to the selected value) should be calculated.
Then, I would like to show my data only for 202106 and 202006 in a pivot table.
