This error indicates that a specific property within a complex type is not properly defined or mapped, leading to a failure in the conversion process.
  Cause:
  
  Missing Mapping: The property &2 in the complex type &1 is not mapped correctly or is missing in the OData service definition.
  Incorrect Metadata: The metadata for the OData service may not be correctly defined, leading to inconsistencies in the expected structure of the complex type.
  Model Definition Issues: There may be issues in the way the complex type is defined in the ABAP backend, such as missing fields or incorrect data types.
  Reference Property Issues: The reference property &3 may not be correctly defined or may not exist, causing the conversion to fail.
  
  Solution:
  
  
  Check OData Service Definition:
  
  Go to the SAP Gateway Service Builder (transaction code SEGW) and check the definition of the complex type &1.
  Ensure that the property &2 is defined and correctly mapped to the corresponding data element in the backend.
  
  
  
  Review Metadata:
  
  Use transaction code /IWFND/MAINT_SERVICE to check the metadata of the OData service.
  Ensure that the metadata reflects the correct structure of the complex type and its properties.
  
  
  
  Adjust Model Definitions:
  
  If you have access to the ABAP backend, check the data model and ensure that all properties of the complex type are correctly defined.
  Make sure that the reference property &3 is also defined and correctly linked to the complex type.
  
  
  
  Regenerate the Service:
  
  After making any changes, regenerate the OData service in the Service Builder and activate it.
  Test the service again to see if the error persists.
  
  
  
  Debugging:
