Field '&1' is not compatible with a BW InfoObject

What causes this issue?

All fields of the default View Node must be of type "BW Element". Field
&V1& in default View Node &V2& is not of this type (i.e. a pure HANA
View field) and thus cannot be a field in a BW InfoProvider.

System Response

The model back end has suspended the model check because the
CompositeProvider model is inconsistent. This model cannot be activated.

How to fix this error?

Fix the model and re-check.
