Just return false in the PreExport script and the job will fail.
You will get the following job error:
"User script function PreExport returned false"
This will cause a SystemAlertJobFailed event to be fired.
For example I want to compare the last modified dates of the Import and Export files and stop the process from running if the Import file has not been modified since the last export.
Thanks for any help. /b[/quote]
