Hi all, I have a question about CDS view.

Does CDS view calculate and buffer data on ABAP server level or on DB level?

Both. If you are able to switch on buffering, data are buffered, when accessed with Open SQL. Otherwise all is done on DB.

Thank you for the reply.

BTW, would CDS view do data pre-selecting at the beginning of the ABAP program, which mignt be better than Open SQL in terms of performance?
