Hi Cristina,
Good to know that it works now.
I hope my answer helped you to some extent.
Reason I suggested you not to make changes to standard configurations but to create the copy of standard segmentation object and HANA view is that there is no issue even if anything gets messed up, we still have the standard delivered content with us.
Also during upgrades, its easier to manage your own content rather than the changes which you make to standard content.
I prefer using copy of standard HANA views and not making changes to standard Configurations.
Regards,
Nidhi
