BOPF and Web Services in ERP

Hello.

In BOBX configuration I see the fields with title "proxy" everywhere. This leads me to believe that the following two scenarios should be supported:

1) Expose BOPF as web service to the outside world.

2) Consume web service through BOPF.

This could in a way be deducted in ERP EHP6 when looking at the BO category "message" and comparing to category "business object". In EHP7 this message BO category is no longer there.

Also, there is a deactivated function that generates customizing for a buffer class CL_BOPF_BUFFER_SPROXY that does not exist.

So what is the support for the above scenarios in ERP EHP7? Also, is there a buffer class so that we can read a web service message through its proxy?

Kind Regards

Martin
