• What is the cause and solution for SAP error message /IWBEP/CM_CP215 - Navigation properties are currently not supported for select ('&1') ?

  The SAP error message /IWBEP/CM_CP215 indicates that navigation properties are not supported for the specific SELECT operation you are trying to perform in an OData service. This typically occurs when you attempt to access related entities through navigation properties in a way that is not supported by the underlying data model or the OData service implementation.
  Cause:
  
  Unsupported Navigation: The OData service may not support navigation properties for the entity you are trying to access. This can happen if the service is not designed to handle complex queries involving related entities.
  Service Configuration: The OData service might not be configured to expose navigation properties, or the navigation properties may not be defined correctly in the service metadata.
  Query Structure: The structure of your OData query may be incorrect, such as trying to access a navigation property that does not exist or is not accessible in the context of the current entity.
  
  Solution:
  
  Check Service Metadata: Review the OData service metadata (usually accessible via the $metadata endpoint) to confirm whether the navigation properties you are trying to access are defined and supported.
  Modify the Query: If navigation properties are not supported, consider restructuring your query to retrieve the data you need without using navigation properties. You may need to perform multiple requests to get related data.
  Update Service Implementation: If you have control over the OData service implementation, consider updating it to support navigation properties if that aligns with your business requirements.
  Consult Documentation: Refer to the SAP documentation for the specific OData service you are using to understand its capabilities and limitations regarding navigation properties.
  
  Related Information:
  
  OData Version: Ensure that you are using the correct version of OData that your service supports, as different versions may have different capabilities regarding navigation properties.
