Get how many tickets were generated in the month before the chosen one
Hello Community! I'm just entering what is Qlik Sense and I have a doubt that I can not solve it for several days.
I want to get how many tickets have been made in the month before the one chosen. For example, I choose the month March of the Year 2018, and I want to show the Number of Tickets for March and also, for February.
The code to appear the previous month, I can not find it. I attach the data.
