Error when extracting data from IBP Keyfigure

Hello,

I am running into below error when extracting data from a Keyfigure in IBP 5.0.

Reader Target_Query

                                                               Data Services Engine received error message from server.  URL: https://integration.onDemand.com/DSoD/agentmanager/reader, Error

                                                               message:  Failed to read from HANA Cloud Source DataStore : Error in executing SQL conversion stored procedure:  (cause: SAP

                                                               DBTech JDBC: [258]: insufficient privilege: Not authorized).

What could be the missing piece?

Thanks,

Kiran
