How to compare all-time monthly values and output percentage changes ?

[PowerBiGuru2]

Hello Community,

I am experiencing difficulty creating a DAX Command that compares my monthly averages and percentage changes. I need to see all-time average rather than the average for the month. I will include the information below. I need to display the % change in a table with the following columns:

Product Identification, (All time - 2022-9), (All time - 2022-10), and % change.

I do not own the live dataset.

Any help would be greatly appreciated. I will provide images below.

Thank you!

Best,

Hi, @PowerBiGuru2 

I failed to complete the understanding. What do you expect the output to be? Is it possible to expand your sample data and expected output in Excel?

Hello @v-zhangti,

Thank you for your response. I have attempted building Excel pivot tables to accomodate my needs. Unfortunately, that was not ideal as my "... code" would not match the two separate date ranges.

I have provided an image below to further identify my objective:

Due to keeping the anonymity, "... Code" serves as my replacement identifier (highlighted in black). In yellow are the numbers I need to compare in order to output a % change. The logic would be as follows:

"A12... Code"    All time - September = 4.71     All time - October = 4.71     4.71-4.71 = 0    0/4.71 = 0.00%

The 0.00% should be the new column output.

Thank you!
