Hi Diego,
Here is the information that I know -
1. Database user should have 'Owner' rights of the database.
This KBA will also help you.
KBA1705522 - What are the permissions needed for the CMS database - SAP BusinessObjects Intelligence Platform 4.0?
2. We have to set the oracle table space to 'Auto Extend' .
.Refer KBA 1262903 - How to increase table space for oracle repository ?
Hope this helps.
Regards,
Rukaiya
