Thanks Prithviraj for your reply.
I have checked both the SAP notes but ain't of much help.
SAP note 1248769 - The view /SSB/CACHECONV doesn't exist in database. But I can't get into edit mode for the view /SSB/CACHECONV in SE14, probably because the status of this view is currently "upgrade" state.
SAP note 1624942 - this note is not applicable for the issue I am facing.
