Hi,

I have references on sheet 1 column A and I have part of these references
on
sheet 2 column A as well. On Sheet 1 column B, I want to put "Yes" for
references on sheet 1 which match references on Sheet 2 and "No" for
otherwise.

N.B: There might be several rows with the same referece on Sheet 1, while
on
sheet 2 there is a unique reference for each raw.
