Bill has already pointed out that the Publisher will not execute certain triggers.
However there is a workaround to this. Basic principle is:
1) Create a CMD file on the QlikView Server that will start the reload
2) Create a Windows task that will run the CMD file
3) Create a CMD file that calls the Windows Scheduler
4) In the QMC go to 'Systems' tab, select 'Supporting Tasks' and 'External Programs' and create a new external program task. On the 'Triggers' tab of the just created task, it can be attached to any other existing task.
Hope this helps!
