So I currently have a formula that determines the year over year % change. However, in my dataset, the following years are used:
2019, 2021, 2022, 2023. The formula works perfectly for all the years except the 2019-2021 change. How could I modify the below formula to calculate the change from 2019-2021 instead of 2020-2021. In other words, how can I make the DAX ignore a year if there is no data for that year. Below is the formula I am using. Thanks in advance!
