Dynamically find the previous 3 months average
Hi All,
I'm newbie to this forum and here is my first post. I am trying to create a column that shows the prev 3 months avg.
forecasted dynamically. Evey new months added to the table automatically will calculate the previous 3 month average. ex. for April will calculate the previos average of Feb, Mar and Apr while for June will calculate the previous avg of May, April and March.
To get the Total Good% and IN Process% here is the formula:
Total Good% = Total Good / Total IN
IN Process% = IN Process / Total IN
To find the previous 3 Months avg the formula is: ( Total Good% * prev. 3 months average of Total Good%) + TOtal Good%

Could someone help me to find a solution or idea using DAX expression. By the way, I'm new in PBI and DAX. Thanks.
Below is a sample data
dt total IN Total OUT Good OUT% Good% 3MonthsFcst 2/1/2019 79606 51384 0 0.65 0.00 3/1/2019 84194 61211 0 0.73 0.00 4/1/2019 92458 67807 0 0.73 0.00 5/1/2019 94531 66988 95 0.71 0.10 70.93% 6/1/2019 29832 18181 2903 0.61 9.73 67.98%
Hi Anonymous - I just noticed this hadn't had much traction and took a look and it seems like a DAX problem rather than something that needs developer focus. You might get a faster response in the DAX Forum of the community, as a lot more people frequent that one and are more readily available to assist you.
