RegisterWithGeodatabase problems (Error 999999)

[IgorReuter]

I'm trying to register with geodatabase a view created with objectid and shape fields that joins an alphanumerical table. I've tried it by ArcMap, Python 32 bits (python window in arcmap) and Python 64 bits (arcgis server), but all they returns the same error:

What I'm doing wrong, or how can I get a more specifc error message?

All plataforms used are in 10.5 version: ArcGIS Enterprise, ArcMap and ArcSDE.
