Hi Atul,
We upgraded HANA system from version 28 to 62 or 65. I am not sure but will check with Basis team about ECC or SLT kernel update.
Also, After HANA system upgrade...when i run Webi report in BO on top of HANA DB, I am getting "RDBMS is invalid error"... I have already configured HDBODBC32 connectivity for HANA.
Regards,
Komik Shah
