This error indicates that the system is unable to find a specified complex type in the metadata of the OData service. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Missing Complex Type Definition: The complex type referenced in the error message is not defined in the data model of the OData service.
  Incorrect Service Registration: The OData service may not be properly registered or activated in the SAP Gateway.
  Model Issues: There may be issues with the data model or the service implementation that prevent the complex type from being recognized.
  Namespace Issues: The complex type may be defined in a different namespace that is not being referenced correctly.
  
  Solutions:
  
  
  Check the Data Model:
  
  Ensure that the complex type is defined in the data model of your OData service. You can do this by checking the service's metadata (usually accessible via the service URL with $metadata appended).
  If the complex type is missing, you may need to add it to the data model.
  
  
  
  Rebuild the Service:
  
  If you have made changes to the data model, you may need to regenerate the service. This can be done using transaction code /IWFND/MAINT_SERVICE to maintain the service and ensure it is properly activated.
  
  
  
  Check Service Registration:
  
  Ensure that the OData service is correctly registered in the SAP Gateway. You can check this in the SAP Gateway Service Builder (transaction code /IWFND/SEGW).
  Make sure that the service is activated and that the relevant entities and complex types are included.
  
  
  
  Review Namespace:
  
  Verify that the complex type is being referenced with the correct namespace. If the complex type is defined in a different namespace, you may need to adjust the references accordingly.
  
  
  
  Debugging:
  
  If the issue persists, consider debugging the OData service to trace where the error occurs. This can provide insights into why the complex type is not being found.
  
  
  
  Check for Transport Issues:
  
  If the service was recently transported from one system to another, ensure that all necessary objects (including complex types) were included in the transport request.
