• What is the cause and solution for SAP error message /IWFND/MED_CHECK009 - Default operation '&1' not defined as operation ?

  The SAP error message /IWFND/MED_CHECK009 Default operation '&1' not defined as operation typically occurs in the context of SAP Gateway and OData services. This error indicates that the system is trying to access a default operation (like GET, POST, PUT, DELETE) that has not been defined for the OData service or entity set in question.
  Cause:
  
  Missing Operation Definition: The specified operation (e.g., GET, POST) is not defined in the service's metadata.
  Service Registration Issues: The OData service may not be properly registered or activated in the SAP Gateway.
  Incorrect URL: The URL being accessed may not correspond to any defined operation in the OData service.
  Authorization Issues: The user may not have the necessary authorizations to access the operation.
  
  Solution:
  
  
  Check Service Metadata:
  
  Use the transaction code /IWFND/MAINT_SERVICE to check if the OData service is properly registered and activated.
  Review the service metadata (usually accessible via the service URL with $metadata appended) to ensure that the operation is defined.
  
  
  
  Define Missing Operations:
  
  If the operation is missing, you may need to define it in the service implementation. This can be done in the Service Builder (transaction code SEGW).
  Ensure that the relevant methods (e.g., GET_ENTITY, GET_ENTITYSET, etc.) are implemented in the corresponding Data Provider Class (DPC).
  
  
  
  Check URL and Parameters:
  
  Verify that the URL being used to access the OData service is correct and matches the defined operations.
  Ensure that any required parameters are being passed correctly.
  
  
  
  Authorization Check:
  
  Ensure that the user has the necessary authorizations to access the OData service and its operations. This can be checked in transaction SU53 after the error occurs.
  
  
  
  Regenerate and Activate the Service:
  
  If changes were made to the service definition, regenerate the runtime artifacts and activate the service again in the Service Maintenance transaction.
