• What is the cause and solution for SAP error message /IWFND/MED_SVC_MU_LA010 - Default operation '&1' is not type Q (Query) ?

  The SAP error message /IWFND/MED_SVC_MU_LA010 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 a particular service is not of the expected type, which should be a Query operation (type Q).
  Cause:
  
  Incorrect Operation Type: The operation defined in the OData service is not set as a Query operation. It might be defined as a Create, Update, or Delete operation instead.
  Service Definition Issues: There may be issues in the service definition or metadata where the operation is not correctly defined or mapped.
  Service Implementation: The implementation of the service might not align with the expected operation types, leading to this error when the service is invoked.
  
  Solution:
  
  
  Check Service Definition:
  
  Go to the SAP Gateway Service Builder (transaction code SEGW).
  Open the relevant service and check the entity set and its operations.
  Ensure that the default operation is set to Query (type Q).
  
  
  
  Adjust Operation Types:
  
  If the operation is incorrectly defined, you may need to adjust it to ensure it is set as a Query operation.
  You can do this by right-clicking on the operation in the service builder and selecting the appropriate type.
  
  
  
  Regenerate the Service:
  
  After making changes, regenerate the service to ensure that the changes take effect.
  Use the Activate option in the service builder to activate the service.
  
  
  
  Check Metadata:
  
  Ensure that the metadata of the OData service reflects the correct operation types.
  You can check the metadata by accessing the service URL with $metadata appended (e.g., http://<host>:<port>/sap/opu/odata/sap/<service_name>/$metadata).
  
  
  
  Test the Service:
  
  After making the necessary changes, test the service again to see if the error persists.
