Extended node in Analytics

From 1511 release onwards it is possible to include extended node in the Datasource as mentioned at: http://scn.sap.com/docs/DOC-68674 with Description "Node Extensions -Usage in Analytics".

But, the extended node cannot be enhanced into the standard datasource, you could instead :

create new datasource on the Standard BusinessObject and

then join the custom datasource with the standard datasource.

Thanks, Pradeep.
