I have a requirement where in i have to exclude the year 2020 while calculating the cy projection sales for 2024. Hence when i calculate, i choose a last 5 year period (2019-2023). However in this last 5 year period 2020 gets included. I need to calculate for all years excluding 2020. How do i do this?
also for the last 5 yr period since im excluding 2020, my last 5 yr period should pick the time range from 2018 - 2023 (excluding 2020)
