  The SAP error message /IWBEP/SBOD411 Navigation Property Path must not be initial typically occurs in the context of SAP Gateway and OData services when there is an issue with the navigation property path in your OData service definition. This error indicates that the navigation property path being referenced is either not defined or is empty (initial).
  Cause:
  
  Empty Navigation Property: The navigation property path that you are trying to use in your OData service is not defined or is empty.
  Incorrect Configuration: There may be a misconfiguration in the OData service or the underlying data model that leads to this error.
  Model Definition Issues: The data model may not have the necessary relationships defined, or the navigation properties may not be correctly set up in the metadata.

  Check Navigation Properties: Ensure that the navigation properties are correctly defined in your data model. You can do this by checking the entity types and their relationships in the OData service definition.
  Update Service Metadata: If you have made changes to the underlying data model, make sure to regenerate the service metadata. You can do this by using transaction code /IWFND/MAINT_SERVICE to maintain your OData service and refresh the metadata.
  Review Service Implementation: If you are implementing custom logic in your OData service, ensure that you are correctly handling the navigation properties in your code.
  Test with Different Clients: Sometimes, the issue may be with the client consuming the OData service. Test the service using different clients (like Postman or SAP Gateway Client) to see if the error persists.
  Check for Initial Values: If you are programmatically setting the navigation property path, ensure that it is not being set to an initial value inadvertently.
