Unable to post 'Create Deep insert' with Json

Hi Expert,

We are using Net weaver Gateway sp9. I searched some blogs which asks me to apply note 1751991 -(OData Channel - Deep Insert in JSON Format Leads to Error) which is not applicable for sp9.

I am able to post a simple structure with out any child nodes.

When I tried to post deep insert with json format, I face an error with bad request.

Following are the header requests I used:-

Content-Type   "application/json;odata=verbose"

x-csrf-token    ay4ubm9vcjpJbml0aWFsMQ==

DataServiceVersion:2.0;

Can any one help me..

Thanks
