Hi Fernando, Melissa What version are you using for engine and dwh? https://bugzilla.redhat.com/show_bug.cgi?id=1344935 Versions: ovirt-engine-dwh-setup-4.0.2-1.el7ev.noarch ovirt-engine-setup-4.0.2.6-0.1.el7ev.noarch should not have this issue. Please update me if you still have this issue and attach the ovirt-engine- dwh log.
