• What is the cause and solution for SAP error message /IWBEP/CM_V4_MED056 - Parameter '&1' is not EDM-based ?

  The SAP error message /IWBEP/CM_V4_MED056 Parameter '&1' is not EDM-based typically occurs in the context of SAP Gateway and OData services. This error indicates that a parameter being used in an OData service is not defined as an EDM (Entity Data Model) type, which is required for the service to function correctly.
  Cause:
  
  Non-EDM Parameter: The parameter specified in the error message is not defined in the Entity Data Model. This could happen if the parameter is not part of the entity or if it is incorrectly defined in the service metadata.
  Incorrect Mapping: There may be a mismatch between the OData service definition and the underlying data model, leading to parameters being referenced that do not exist in the EDM.
  Service Definition Issues: The OData service might not be properly configured to expose the required parameters.
  
  Solution:
  
  Check Parameter Definition: Verify that the parameter mentioned in the error message is correctly defined in the OData service's metadata. Ensure that it is part of the EDM and has the correct data type.
  Update Service Metadata: If the parameter is missing, you may need to update the service definition in the SAP Gateway. This can involve:
  
  Modifying the data model to include the parameter.
  Regenerating the service metadata.
  
  
  Check Service Implementation: Ensure that the implementation of the OData service correctly handles the parameters. This includes checking the methods in the service that process the incoming requests.
  Test the Service: After making changes, test the OData service using tools like Postman or the SAP Gateway Client to ensure that the parameters are now recognized and processed correctly.
  Consult Documentation: Refer to SAP documentation for OData services and the Entity Data Model to ensure compliance with best practices.
