embed one node into another

Hi,

I embed one context node into another to define a nested structure, like the following definition. But it is found that Web Dynpro still takes them as two individual context nodes. Most of the fields from one structure and I don't want to add each field manually to the context node. Also, I don't want to create a structure at SE11 only for this. What are possible alternatives?

TYPES: BEGIN OF typ.

               INCLUDE TYPE MARA.

TYPES: f1 TYPE xxx

           , f2 TYPE xxx

             END OF typ

           .

Best regards,

ts
