Why do reports take much longer to generate results under Reports and Jobs as compared to Advanced Reporting?
When a report is run under Reports and Jobs in PPM, either immediately or scheduled, it always runs behind the scene as scheduled. The Jaspersoft scheduler API then is used to execute the report in Jaspersoft and keeps it under the Jaspersoft Repository - CA PPM - Reports Output folder. A continuous polling is done between PPM and Jaspersoft to check if the report is completed, once a report is complete,  PPM then copies that output file (excel/PDF/Word) from Jaspersoft to the PPM File store (could be Database/Normal File store) and shown under Report Library and hence there will be a lag.
