Several tables at once from backend

Hi Folks,

I'm just wondering, is it possible to retrieve two tables at once from the backend.

To avoid to much traffic I want to retrieve more tables at once from the backend.

Normaly I have for each table an odata Service, so I connect for each table to the backend.

Of course I could put all data in one table and split it off in eclipse.

But it would be better when I could two tables Independent.

Any clues?

Thanks and Rg. Joerg
