Not able to convert Simulink.Bus object using Targetlink

I have a stateflow in my mdl file. One of the out signal from this stateflow is a structure and its data type is declared as Bus object. I am using targetlink to generate autocode.

While generating autocode, I am getting error as follows: Error#03087: Unknown value for .props.type.method: 17.SF object handle: 2022.

Is it because Targetlink does not support Simulink.Bus object? How to solve this issue for successful code generation?

Thanks in advance, Hemarajan Chikorde
