# ViewToContainerMappingNotPossible validation rule

> Validates that the container and container property referenced by each view property exist. Ensures the data model can be deployed to CDF.

This rule checks that, for each view property that maps to a container and container property,
the referenced container and container property exist.

## Why it matters

If a view property references a container or container property that does not exist,
the data model cannot be deployed to CDF. This means that the view property cannot function.

## Example

The `WindTurbine` view has property `location` that maps to container `WindTurbineContainer` and property `gpsCoordinates`.
If `WindTurbineContainer` and/or property `gpsCoordinates` does not exist, the data model cannot be deployed to CDF.
