Hi Uruj Pruthi,
As Ashmi mentioned, if you are using BO, please run the Update Business Objects Table job. If you are using Jaspersoft and is on CA PPM 14.4, check this please
CA PPM(Clarity) Tuesday Tip: Jaspersoft reports(Advanced reporting) returns with no records after the upgrade to 14.4
If the above does not fix the problem, please let us know
Clarity PPM version?
Jasper/BO?
Is this happening against all projects/resources or only a few of them?
Did this started happening all of a sudden, may be after an upgrade or patch?
If its jaspersoft, I am assuming that you have ran the Load DWH job.
Thanks,
Jerin
