here is the question:
A CDS view is referenced in SEGW, and i would like to add a eTag for this entitytype, the whole program logic is maintained by BOPF. i think what is the easiest way to achieve this is by adding annotation in CDS View. And of course i have tried in that way, however, the field still not shown in the eTag field in SEGW.
the link below is i refered to:
is this the right way to solve this or there is another better way to do so?
