Hello Saurabh,
_SYS_BIC is a system user and the schema is a system generated schema. We should not create user objects like tables there. The _SYS_BIC schema holds column views of the modelling objects(attr,. views, calc. views etc) that you create in the content folder. The column views in _SYS_BIC are the ones that are exposed to the reporting tools.
Please create your table in some other user defines schema and model your view on it. Once activated, you can see your view in the column view folder of _SYS_BIC. Which you can use in Lumira
