Using RAP to build Side-by-Side extensions

[skopp]

Hi everybody,

is there any way to build a Side-by-Side Extension in RAP on BTP without using an unmanaged scenario when reading from an on premise system? Can't seem to find anything about it. 

I hope there is an easier way to consume the APIs and to re-use their functionality.

What is the benefit when I have to implement the whole logic of the business object again on BTP?

That is exactly what I did.

But that's what I meant with implementing it all again (in this case in the Query Implementation Class).

This works of course, but I have to take care of data retrieval, update, creation, validation and so on again and can't reuse the business object logic (which is already implemented in the on-prem system).

I would disagree. I do not see why you have to redo everything again. You can expose actions, validations, determinations and reuse them.

That would be great. Is there any documentation or tutorial, mission etc. about it? I can't seem to find anything that explains the process.
