  The SAP error message /IWFND/MED_CHECK010 Default operation '&1' is not type Q (Query) typically occurs in the context of SAP Gateway and OData services. This error indicates that the default operation defined for an OData service is not recognized as a query operation, which is expected for certain types of requests.
  Cause:
  
  Incorrect Operation Type: The operation defined in the OData service is not of type "Query" (Q). This can happen if the operation is defined as a "Create", "Update", or "Delete" operation instead of a "Read" operation.
  Service Definition Issues: There may be issues in the service definition or the metadata that do not align with the expected operations for the OData service.
  Implementation Errors: If the service implementation does not correctly handle the expected operations, it may lead to this error.
  Service Registration Issues: The service might not be properly registered or activated in the SAP Gateway.
  
  Solution:
  
  Check Service Definition: Review the service definition in the SAP Gateway Service Builder (transaction code SEGW). Ensure that the default operation is correctly defined as a "Query" operation.
  Adjust Operation Types: If the operation is incorrectly defined, adjust it to be of type "Query". This may involve modifying the service implementation or the data model.
  Review Metadata: Check the metadata of the OData service to ensure that the operations are correctly defined and that the service is exposing the expected entities and operations.
  Re-register the Service: If changes were made, re-register the OData service using transaction code /IWFND/MAINT_SERVICE. Ensure that the service is activated and properly configured.
  Test the Service: After making the necessary changes, test the OData service using the SAP Gateway Client (transaction code /IWFND/GW_CLIENT) to ensure that the error is resolved.
