Its 15.2 version CA PPM, Jasper - 6.2.1.
when I scheduled the report after I receive the email that report run has "PASS" after couple of minutes i used to get the email having the report extract attachments.
In this case the report attachment was not sent and the report extract is not placed at the destination folder.
We can assume that if the report extract was more than 25 MB , which cannot be attached in emails, but I don't think there is limitation with the destination folder.
Yes Stack trace was checked during report schedule.
