It was found that on a newly created V9 environment the view BMC_CORE_BMC_SYSTEMCOMPONENT was not valid. This is an out of the box view but the view that it is based on - T3784 underpinning BMC.CORE:BMC_SystemComponent was missing.
The view was broken or Invalid.
In order to restore the View, added a Display only attribute from Class Manager and allowed it to Sync.
This newly added attribute helped restoring the Broken view for the specified Class.
Also please refer KA(000128356 ) which talks about the views getting invalid in Oracle Database.
The same steps can be followed to restore any deleted or missing attributes which is present in the BMC_BaseElement class but is missing from it's child classes.
