Specifically, it states that the base complex type (&1) of the complex type (&2) does not exist. This typically occurs in the context of OData services when there is a mismatch or misconfiguration in the data model.
  Cause:
  
  Missing Base Type: The base complex type that is referenced in your complex type definition is not defined or is not available in the system.
  Incorrect Mapping: There may be an issue with the mapping of the complex types in your OData service definition.

  Transport Check: If the service was transported, ensure that all necessary objects, including the base complex type, were included in the transport request.
  Adjust Model: If there have been changes to the underlying data model, ensure that the OData service is updated accordingly. This may involve adjusting the service definition or re-creating the service.
  Check for Errors in the Data Model: Use transaction SE11 to check the definitions of the complex types and ensure that they are correctly defined and active.
