How to populate a line item using formula with correct time scale in weeks.
Future year sales⬇️
Last year Sales ⬆️
I have two modules SYS9 Last year sales in which I have uploaded values by importing data and other module SYS10 FY22, FY23 & FY24 sales in which uplift value or % which is applied on previous sales value to give the future year sales value.
In SYS10 module I have a line item Previous Year week through which FY22 sales value is fetched.
So how can we populate Previous year week line item using formula such that all the last year week must correspond with the page with current year.
eg. - in pages it is Week 5 FY23 so all the cells under Previous year week should be Week 5 FY22
For Week 6 FY23 all the cells under Previous Year week must be Week 6 FY22.
