Scheduler, error codes

These codes are found in the Windows system application log (event viewer) for the WTScheduler service.

When a scheduled task has failed, in Last run result column, the error code is reported. If error code is 21, it means that the .ROB script has ended with errors. It's possible to see the full error message and the line which failed clicking Application log button. It opens Event viewer, double-click Application on the right pane and open the WTScheduler line for the script which failed.
