The job has not run successfully, there is an error, written to your trace file: "the system cannot find the path specified".
That's due to the backslashes used in the folder path. The backslash is used as an escape character in DS scripting. Try to print('\\frgows55\BODS_Target\NAFTA\script_bods.bat') and see what happens.
Use exec('cmd','\\\\frgows55\BODS_Target\NAFTA\script_bods.bat',8);
