Matrix Column Head Order

Hi srisiva55 ,

You can create a dimension table with the proper orders as below:

Then sort the column [Year] by [Order], create a visual as below screenshot. Please find the details in the attachment.

In addition, you can refer the following link to get it:

Sort a Column with a Custom Order in Power BI - RADACAD

If the above one can't help you, could you please provide some raw data in your table (exclude sensitive data) with Text format and your expected result with backend logic and special examples? It would be helpful to find out the solution. You can refer the following links to share the required info:

How to provide sample data in the Power BI Forum

And It is better if you can share a simplified pbix file. You can refer the following link to upload the file to the community. Thank you.
