No you don't - %KDS has an optional parameter that lets you specify how many of the key fields in the DS to use.

That said I still prefer listing the keys on the opcode.

Also, personally I prefer the individual key fields because, suppose you
want to chain a record that would need a partial key value, in that case
you'd have to code a separate DS for that scenario. While the former, lets
you only add or rip out key fields, depending on your need.
