ABAP CDS Keys

[Former Member]

Hello,

What is the meaning of a key in CDS? I mean that when we create a CDS with a new key (and we DONT get the warning message "All fields are evaluated as key field") --> We defined a new key for the table.

When we select from the view it doesn’t "Group by" automatically by the key.So what is the meaning of the key? Is there any performance impacts?

Thanks,

Amir
