Hi Karan,
Thanks for the response....
I can confirm that I have assigned all required HANA role(s) to the user as mentioned in the implementation steps from Fiori apps Libraray.
I have even assigned SELECT grant on Schema _SYS_BIC for user _SYS_REPO.
But still getting the same error.
On reading the trace log more closely, the authorization error occurs on one of the below call
----------------------------------------------------------------------------------------------------------------------------------------------------
procedure: _SYS_BIC.sap.hba.t.rtl.car.mcsa.v/NumberOfTransactionsHdr/proc variable: VAR_OUT line: 90
----------------------------------------------------------------------------------------------------------------------------------------------------
which is reflects below in error log as
----------------------------------------------------------------------------------------------------------------------------------------------------
failed with rc 258; insufficient privilegeinsufficient privilege: Not authorizedPlease check lines: 90,44,70,4,7,12,5,
----------------------------------------------------------------------------------------------------------------------------------------------------
If that provides more information.
Regards,
Kamal Sehrawat
