Hi Wilfried,
Looks like a rights issue on the user "LUMIRA". I am assuming you are using the same user to acquire this HANA online datatset, and now you are trying to publish the story back to the same Lumira server. Can you check whether this user has the following roles:
sap.bi.common::BI_DATA_ANALYST
sap.bi.common::BI_DATA_CONSUMER
Can you also try a different user, like SYSTEM to see whether this works?
For debugging, it's the BO_trace.ini that controls the trace log level. Check the log_dir parameter to see where the logs are written to.
Regards,
Kai
