RFC Adaptive Model Questions

Hi all,

I have some questions about RFC Adaptive Model in Web Dynpro:

1)Can I add a new RFC into a Model without recreating that?

2)There’s a way to WebDynpro don’t lost de mapped attributes like an input field that’s mapped to an import parameter of a RFC? Because all the times that I change the Model and recreate that, my application lost the link between Controller and View and it’s generate a lot of work to redo this manually.

Thanks,

Manoel
