PPA Build - 5.0 Sp2 RU3h
The Aspect "License Usage" under (Admin structure,Domain,Aspect Type) is showing Empty.
But there are no License errors in License Status Viewer..
What can be the reasons? How to resolve this?

As Boris wrote, the License Usage aspect is not critical.
Personally, I prefer using the License Assignment Editor -> Diagnostics function since it also tells to what node a license has been allocated. Furthermore, the LAE is IE based, i.e. you can call it from any node in the system by supplying the URL which you can find in the CLS node's start menu -> Program -> ABB Industrial IT System 800xA -> System -> Licensing -> License Assignment Editor.
If also the LAE is not working; check that HTTP traffic is allowed between your node and the CLS. An incorrectly configured firewall can prevent HTTP communication. Also incorrect use of Internet Proxy can be a reason, HTTP traffic to CLS should be excempted from proxying.
Is the Central Licensing System Extension correctly reported in the list of System Extensions (Installed on this node AND Successfully loaded)?
The license Usage aspect shows you information of your system but is not crucial in the validation of the license, this is done by the License server with the Licensing client agents. Hence the reason why you are not getting any license violations.
The license usage aspect as I recall was first implemented in SV5.0, not 100% sure it was avaialble with your version but I believe so. Perhaps it was just not available at that time.
You can also check that your internet browser is correctly configured according to the installation manuals. the ie browser configuration has direct influence on the visbility of some aspect information in the system.
