Hi all,
very happy to find this post, it almost the most valuable post, i see till now about hana:) It hits lots of issue I met in project.
I have still one question about the projection nodes after analytic view and union. Rajarshi mentioned, it could narrow down the results. Is there benefit on performance with narrow down? As I understood, hana will generate the executed calculation model based on the designed model and the current query on the model. Regardless how many columns are involved in the designed model, if the query doesn't touch those columns, they are not read from table by hana. That means the narrow down will be done automatically.
Is this true from your option? Thanks!
