Thank you ayman mohammed adam for your response. the file by this name was in a slightly different location and does not contain the same coding. I will look into this file and see if I can arrange a sort order within it.
Thank you also Fabrice Henrion for wanting to make a comment as well, however I am aware of the customer statement report.
My version is "Version 9.0c-20160919 (Community Edition)"
What I am referring to as the "Due Payment" report is when you open Accounting>Customers then open a particular customer at the top under the "Print" drop down next to the "Actions" drop down is "Due Payments". If you would care to comment as to why this generates a report that appears to be in a completely random order and how one might sort this into a more understandable format, please feel free to do so.
Thank you both again for your comments.
