Hi Murat,
In RSRT if you enter the query and goto the "Execute and debug" button on the bottom right Hand corner of this button there is a tiny arrow if you click on this you get an "execute and explain" option, if you click on this there is the option "Exception aggregation in SAP HANA/BWA" please flag this option and click on continue. If you enter the selection criteria and execute the query as normal when the result is returned if you click on the Green back arrow you should get a screen that tells you what exception aggregation was /was not pushed down to HANA. I can only assume there is something in the design of the query that prevents it from being pushed down to HANA.
If you click on the query "properties" button in RSRT under ops in BWA/SAP HANA is the option 6 selected "exception aggregation"?
If you can also attach a screenshot of the output for the execute and explain result it would be great.
Thanks,
Des
