OData batch request and RAP LUW

Hi all,

I have some questions regarding OData batch request and RAP LUW.

If I understand correctly, in http request body, every boundary could have several changesets, these changeset are in one LUW, and every boundary is corresponding to an LUW. First, I am wondering if this is right.

Further, in association case, let's say header entity A and item entity B, if I want to create or update A with B, how should I generate the request body?

1, Complex JSON A with B as an attribute

2, JSON A in changeset 1 and JSON B in changeset 2

Which is the correct one?

In case of 2, how RAP framework calls one method (modify) with both entity A and B? In other words, how the framework knows A has relationship with B if they are in different changesets?

Regards,
Eric
