  The SAP error message /IWBEP/CM_MGW_RT063 Filter parameter '&1' is not supported typically occurs in the context of SAP Gateway and OData services. This error indicates that a filter parameter specified in the OData request is not recognized or supported by the service.
  Cause:
  
  Unsupported Filter Parameter: The filter parameter specified in the OData request does not match any of the fields or properties defined in the OData service.
  Service Definition Issues: The OData service may not be properly defined to handle the requested filter parameters.
  Version Mismatch: The OData service version may not support certain filter parameters that are available in newer versions.
  Typographical Errors: There may be a typo in the filter parameter name in the request.
  
  Solution:
  
  
  Check the OData Service Metadata: Review the service metadata (usually accessible via the $metadata endpoint) to confirm the available properties and filter parameters. Ensure that the parameter you are trying to use is defined in the service.
  
  
  Correct the Filter Parameter: If there is a typo or if you are using an unsupported parameter, correct it based on the metadata.
  
  
  Update the OData Service: If the filter parameter is indeed required but not supported, you may need to update the OData service implementation to include support for that parameter. This may involve modifying the service definition or the underlying data model.
  
  
  Check for Version Compatibility: Ensure that the OData service version you are using supports the filter parameters you are trying to apply. If necessary, update to a newer version of the service.
  
  
  Debugging: If you have access to the backend, you can debug the service implementation to see how it processes the incoming request and identify why the filter parameter is not recognized.
