We're also experiencing the same problem with the Reload Scheduler after upgrading to to SR3. A possible solution, although not ideal, could be to create a batch file to reload the specific Qlikview report and then add a local scheduled task to run the batch file at the required monthly/weekly intervals. The following code can be used for the batch file:
echo Reloading Report name
"C:\Program Files\QlikView\Qv.exe" /r C:\Your model directory.qvw
As mentioned this is not an ideal work around and I would also like to know if there is a better solution to this?
