  The SAP error message SADL_GW_V4_BUNDLE004 with the description "Proxy Model Name is initial" typically occurs in the context of SAP Gateway and the SAP ABAP programming environment when there is an issue with the configuration or usage of the Service Data Layer (SDL) or the OData service.
  Cause:
  
  Missing or Incorrect Proxy Model: The error indicates that the proxy model name is not set or is empty. This can happen if the OData service is not properly configured or if the model is not defined in the service.
  Service Registration Issues: The OData service may not be registered correctly in the SAP Gateway.
  Incorrect Usage in Code: If you are trying to access a service or model that has not been properly instantiated or defined in your ABAP code, this error can occur.
  Transport Issues: If the transport of the OData service or related artifacts has not been completed successfully, it may lead to this error.
  
  Solution:
  
  
  Check Proxy Model Configuration:
  
  Ensure that the proxy model is correctly defined in the service. You can do this by checking the service definition in the SAP Gateway Service Builder (transaction code /IWFND/MAINT_SERVICE).
  Make sure that the model name is not empty and is correctly mapped to the corresponding data source.
  
  
  
  Service Registration:
  
  Verify that the OData service is registered and activated in the SAP Gateway. Use transaction /IWFND/MAINT_SERVICE to check the status of the service.
  If the service is not active, activate it.
  
  
  
  Review ABAP Code:
  
  If you are using the service in your ABAP code, ensure that you are correctly instantiating the proxy model. Check for any typos or logical errors in your code that might lead to the model being uninitialized.
  
  
  
  Check Transport Requests:
  
  If the service was recently transported, ensure that all necessary objects were included in the transport request and that the transport was successful.
  
  
  
  Debugging:
  
  If the issue persists, consider debugging the code where the error occurs to trace back to the point where the proxy model is being accessed. This can provide insights into why the model name is initial.
