XPAC provides an Event Log that you can use to run in the background of the application while you are running a schedule. You may find the Event Log particularly useful to locate errors in your schedule. See Event Log and Help viewers for more information on how to display and control the Event Log.
Before running your schedule, you will want to filter the results in the Event Log to display the relevant debug results. To do so, right-click anywhere in the Event Log viewer and select Filter from the context menu. Make sure the Debug check box is selected, then click OK.
