You're misunderstanding.
I mean normally, Hill's create the new D/W SKU codes for us i.e. PD-DY-10-1959, PD-DY-11-1960
but you let me use the Hill's SKU codes instead i.e. 1959, 1960.
The print screen below is just an example for the D/W SKU codes.
I apologize for the previous question is too short.
