  The SAP error message /IWBEP/CM_V4S_RUN035 Child position &1 not supported typically occurs in the context of OData services when there is an issue with the navigation properties or the structure of the data being accessed. This error indicates that the child entity or position specified in the request is not supported or does not exist in the context of the parent entity.
  Causes:
  
  Invalid Navigation Property: The child entity you are trying to access may not be defined in the OData service or may not be correctly configured in the metadata.
  Incorrect URL Structure: The URL used to access the OData service may be incorrectly formed, leading to an attempt to access a non-existent child entity.
  Service Configuration Issues: The OData service may not be properly configured to support the requested navigation or child entity.
  Data Model Changes: Changes in the underlying data model (e.g., changes in relationships between entities) that have not been reflected in the OData service.
  
  Solutions:
  
  Check Metadata: Review the OData service metadata (usually accessible via a $metadata endpoint) to ensure that the child entity and its navigation properties are correctly defined.
  Validate URL: Ensure that the URL you are using to access the OData service is correctly formed and matches the expected structure for accessing child entities.
  Review Service Implementation: If you are developing or maintaining the OData service, check the implementation to ensure that the navigation properties are correctly defined and that the service supports the requested operations.
  Update Service: If there have been changes to the underlying data model, ensure that the OData service is updated and re-generated to reflect those changes.
  Check Authorization: Ensure that the user has the necessary permissions to access the child entity.
