Replacement Object / Proxy Object - How to create?

Hello Gurus,

I have a stupid question, but I could not easily find an answer.

SAP Help says about Replacement Object:

http://help.sap.com/abapdocu_750/en/index.htm?file=abenddic_replacement_objects.htm

https://help.sap.com/saphelp_nw75/helpdata/en/12/01f8d4b3e54e6abe111f9f96f19c99/content.htm

"A CDS view can be assigned (using the name of its CDS entity) as a replacement object to a transparentdatabase table and to a classic database view in ABAP Dictionary"

But for me, it's not really clear how it (CDS) can be created or assigned to the table.

If i'm navigating: SE11 --> Extras --> Proxy Object (in fact should be called Replacement Object as per documentation), this field is not changeable for me. I'm on 750 SP3. No failed authorizations checks ( in fact i have SAP_ALL).

Thanks for your help!

BR, Dima
