How to create a service with deep insert input but output a single entity?

Hi Experts,

     I have created a service which has 2 entities.

     DeliveryHeader

     DeliveryItems

     StatusOutput

     Association has been defined for DeliveryHeader and  DeliveryItems.

    My input request message is:

    {

       "DN_No" : "123",

       "ShipTo" : "CNZ",

        "DeliveryItems" : [{

        "DN_No": "123",

        "Item_No": "1",

        "Quantity": "10'

       }]

  }

I want my output to be different entity structure that is of StatusOutput.

{

    "StatusOutput" : {

         "Code": "100",

         "Text" : "Successfully created DN"

}

}

But I am getting output same as input.

What I have to do to get the desired output? Please help!

In my create_deep_entity I have coded like this:

TYPES:  BEGIN OF t_output.

           TYPES: StatusOutputTYPE ycl_prj_create_dn_mpc_ext=>TS_STATUSOUTPUT,

          END OF t_output.

x_output-StatusOutput-code = "100".

x_output-StatusOutput-text = "Successfully created DN".

    copy_data_to_ref(

       EXPORTING

         is_data = x_output

       CHANGING

         cr_data = er_deep_entity ).

Thanks
