Latest Execution Result in RPE

You can do it without using any scripting. Sort on executionresult/endtime in Ascending direction and assign the result to a variable. After the iteration, the variable holds the latest result and you can just print the variable.

Another option is to use an internal variable _isPrinted (with default value 0). Sort on endtime (Descending) and print the result only when _isPrinted="0" as in the screenshot.
