Showing Request and Response in ReadyAPI printable report for each Testcases

curious as to why you might want to do that and the benefit you will get from it? Reports could be come quite large if you are writing all the information to report.

But, a way to do it would be to review/customize the report template (from the Project -> Reporting section)
