The "log_transaction" file is in the site's "etc" directory so yes,
you should have full permission to edit this file in any way that
suits your purpose.  The file will be called from one of your Routes,
usually the "log" route, which is usually defined in your site's
catalog.cfg file.

See the "Order Routing" section of the "Interchange Database" document.
Apart from the mention in that document, there's no specific
documentation that covers the log_transaction file; That file simply
contains Interchange tags.  Look at the "Interchange Tags Reference"
documentation if any of the existing file's contents trouble you.
Ask here if you have any further questions.
