I am having a requirement where I need to place values for current month vs previous month
Date (Year month format)
I have variable set for value in current month, however I am not able to create a proper expression for getting the values from the pervious Year Month. Mainly because of Jan to Dec. If I use 202101 as current Year Month for example, I am getting 202100 as Previous Year Month Date. What expression can I use for when current year month is 202101, the previous year month date will show as 202012?
