  The SAP error message /STTPEC/ODATA018 Navigation property '&1' in entity set '&2' not found typically occurs in the context of OData services when there is an attempt to access a navigation property that does not exist in the specified entity set. This can happen for several reasons, and understanding the cause is essential for finding a solution.
  Causes:
  
  
  Incorrect Navigation Property Name: The navigation property name specified in the request may be misspelled or does not match the name defined in the OData model.
  
  
  Entity Set Configuration: The entity set may not be configured to include the specified navigation property. This can happen if the property is not defined in the metadata of the OData service.
  
  
  Model Changes: If there have been recent changes to the OData model (e.g., adding or removing navigation properties), the client application may not be updated to reflect these changes.
  
  
  Service Versioning: If the OData service has multiple versions, the navigation property may exist in one version but not in another.
  
  
  Authorization Issues: Sometimes, the navigation property may be restricted due to authorization settings, making it unavailable for certain users or roles.
  
  
  Solutions:
  
  
  Check Navigation Property Name: Verify that the navigation property name in your request matches exactly with the name defined in the OData service metadata. This includes checking for case sensitivity.
  
  
  Review OData Metadata: Access the OData service metadata (usually available at the service URL with $metadata appended) to confirm that the navigation property exists in the specified entity set.
  
  
  Update Client Application: If there have been changes to the OData model, ensure that the client application is updated to use the latest version of the model.
  
  
  Check Service Version: If applicable, ensure that you are using the correct version of the OData service that includes the navigation property you are trying to access.
  
  
  Authorization Check: Review the authorization settings to ensure that the user has the necessary permissions to access the navigation property.
  
  
  Debugging: If you have access to the backend, consider debugging the OData service to trace the request and see where it fails.
  
  
  Related Information:
  
  OData Documentation: Familiarize yourself with OData standards and best practices, which can help in understanding how navigation properties work.
  SAP Notes: Check SAP Notes for any known issues or patches related to the OData service you are using.
